We maintain a call center at our headquarters in Santa Clara, California and have a staff of 84 employees and contractors that provide customer service and technical support to customers. In addition, we have outsourced certain customer support activities to third parties. We also provide customer service and technical support directly to our resellers, while some resellers provide their own support directly to their sub-resellers and customers. Customers who access our services directly through our web site receive customer service and technical support through multilingual telephone communication, web-based customer service and e-mail support.

We are party to telecommunications interconnect and service agreements with VoIP providers and PSTN telecommunications carriers, such as our 24-month agreement with Level 3 Communications, which is for domestic services which expires on May 31, 2008 and for international services, which is in effect from March 1, 2007 through May 31, 2008. Pursuant to these agreements, VoIP calls originating on our network can be terminated on other VoIP networks or the PSTN. Correspondingly, calls originating on other VoIP networks and the PSTN can be terminated on our network. While we believe that relations with our suppliers are good, there can be no assurance that our suppliers will be able or willing to supply products and services to us in the future.

The VoIP market is characterized by rapid technological changes and advances. Accordingly, we make substantial investments in the design and development of new products and services, as well as the development of enhancements and features to our existing Packet8 products and services. Future development also will focus on the use and interoperability of our products and services with emerging audio and video telephony standards and protocols, quality and performance enhancements to multimedia compression algorithms, the 802.11 standard and other wireless applications. We also seek to develop new endpoints for subscribers to our services. We believe that the development of new products and the enhancement of existing products are essential to our success.

We currently employ 25 individuals in research, development and engineering activities in our facilities in Santa Clara, California and Sophia Antipolis, France. Research and development expenses in each of the fiscal years ended March 31, 2007, 2006 and 2005 were $4.7 million, $5.9 million and $3.1 million, respectively.

Although several regulatory proceedings are underway or are being contemplated by federal and state authorities, including the Federal Communications Commission, or FCC, and state regulatory agencies, VoIP communication services have remained largely unregulated in the United States when compared to traditional telephony services. To date, VoIP service providers have been mainly treated as information service providers although the FCC has thus far avoided specifically ruling on this classification. Information service providers are largely exempt from most federal and state regulations governing traditional common carriers. The FCC is currently examining the status of VoIP service providers and the services they provide. The FCC initiated a notice of proposed rule-making (NPRM) in early 2004 to gather public comment on the appropriate regulatory environment for IP telephony. In November 2004, the FCC ruled that the VoIP service of a competitor and "similar" services are jurisdictionally interstate and not subject to state certification, tariffing and most other state telecommunications

8

regulations. The FCC ruling was appealed by several states and on March 21, 2007, the United States Court of Appeals for the 8^th Circuit affirmed the FCC ruling.

Interconnected VoIP providers, like us, are required by the FCC to offer 911 emergency calling capabilities similar to those available to subscribers of traditional switched phone lines. Moreover, interconnected VoIP providers were required to distribute stickers and labels warning customers of the limitations associated with accessing emergency services through an interconnected VoIP service, as well as notify and to obtain affirmative acknowledgement from our customers that customers were aware of the differences between the emergency calling capabilities offered by interconnected VoIP providers as compared to traditional, wireline providers of telephone service. The FCC's Enforcement Bureau released an order stating that the Enforcement Bureau will not pursue enforcement against interconnected VoIP providers that have received affirmative acknowledgement from at least 90% of their subscribers. We have received affirmative acknowledgement from substantially all of our customers and have substantially satisfied this requirement of the rule.

Like many interconnected VoIP providers, we currently cannot offer VoIP E911 services that route emergency calls in a manner consistent with the FCC rules for all of our customers. We are addressing this issue with our VoIP E911 Solution providers. On November 28, 2005, we began routing certain 911 calls to a national emergency call center. The emergency dispatchers in this national call center utilize the location information provided to route the call to the correct PSAP or first responder. The FCC may determine that our VoIP E911 solution for these customers does not satisfy the requirements of the VoIP E911 order because, in some instances, we will not be able to connect our subscribers directly to a PSAP. As of April 5, 2007, we provided emergency calling services to 100% of our subscribers located in the United States and 91% of these subscribers are supported with either an E911 solution that is in compliance with the VoIP E911 order or were customers prior to November 28, 2005. We may be subject to enforcement actions including, but not limited to, fines, cease and desist orders, or other penalties for those customers that we are unable to provide E911 service in a manner consistent with the VoIP E911 order.

On June 1, 2007, the FCC released a Notice of Proposed Rulemaking Proceeding to consider whether it should impose additional VoIP E911 obligations on interconnected VoIP providers including consideration of a requirement that interconnected VoIP providers automatically determine the physical location of their customer rather than allowing customers to manually register their location. The Notice includes a tentative conclusion that all interconnected VoIP service providers that allow customers to use their service in more than one location (nomadic VoIP service providers such as us) must utilize automatic location technology that meets the same accuracy standards applicable to providers of commercial mobile radio services (mobile phone service providers). We cannot predict the outcome of this proceeding nor its impact on the Company at this time.

On August 5, 2005, the FCC unanimously adopted an order requiring interconnected VoIP providers to comply with the Communications Assistance for Law Enforcement Act, or CALEA. CALEA requires covered providers to assist law enforcement agencies in conducting lawfully authorized electronic surveillance. Under the FCC order, interconnected VoIP providers were required to comply with CALEA obligations by May 14, 2007 and make certain filings prior to that date. Consistent with the relevant rules, we continue to work with a third-party solution provider to devise a CALEA-compliant solution. As of May 14, 2007, we had installed this solution in our network operations and data centers, but had not yet completed testing of all required intercept capabilities of this equipment. We are diligently working to complete the testing of this equipment in order to achieve full compliance with the FCC's order. We may be subject to enforcement actions including, but not limited to, fines, cease and desist orders, or other penalties if we are not able to comply with CALEA.

On June 21, 2006, the FCC expanded the base of Universal Service Fund, or USF, contributions to interconnected VoIP providers. The FCC established a safe harbor percentage of 64.9% of total VoIP service revenue to which federal USF contributions apply. We were allowed to calculate our contribution based on the safe harbor or by submitting a traffic study that would subsequently be approved by the FCC. For a period of at least two quarters beginning October 1, 2006, we were required to contribute to the USF for our subscribers' retail revenues as well as through our underlying carriers' wholesale charges. Beginning October 1, 2006, we began charging our subscribers a USF surcharge fee equal to the USF contribution amounts we were required to contribute. The FCC order applying USF contributions to interconnected VoIP providers was appealed and on June 1, 2007, the U.S. Court of Appeals for the District of Columbia ruled that the FCC was within its authority when it required interconnected VoIP service providers to contribute to the Universal Service Fund, though it struck down the provision of the order which required pre-approval of traffic studies by the FCC and the provision that required double contributions to the fund for two quarters from our underlying carriers' wholesale charges. While we are still examining the impact of the ruling, we believe that we are entitled to a credit for the two quarters in which we double contributed to USF and for the portion of our contribution that exceeded the percentage of interstate traffic that we produced in our traffic study. We further believe that we will have a reduced USF contribution rate on a going-forward basis. Meantime,

On April 2, 2007, the FCC released an order extending the application of customer proprietary network information, or CPNI, rules to interconnected VoIP providers. CPNI includes information such as the phone numbers called by a consumer; the frequency, duration, and timing of such calls; and any services/features purchased by the consumer, such as call waiting, call forwarding, and caller ID, in addition to other information that may appear on a consumer's bill. Under the FCC's existing rules, carriers may not use CPNI without customer approval except in narrow circumstances related to their provision of existing services, and must comply with detailed customer approval processes when using CPNI outside of these narrow circumstances. The new CPNI requirements are aimed at establishing more stringent security measures for access to a customer's CPNI data in the form of enhanced passwords for on-line access and call-in access to account information as well as customer notification of account or password changes. At the present time we do not utilize our customer's CPNI in a manner which would require us to obtain consent from our customers, but in the event that we do in the future, we will be required to adhere to specific CPNI rules aimed at marketing such services. Effective December 8, 2007, we will be required to implement internal processes in order to be compliant with all of the FCC's CPNI rules. This may impose additional compliance costs on the Company and reduce our profitability or cause us to increase the retail price for our services.

On April 18, 2007, the FCC released a Notice of Proposed rulemaking or Notice tentatively concluding that providers of interconnected VoIP services, like us, should pay regulatory fees. According to the Notice, the FCC would like to begin collection of such fees in the August to September 2007 timeframe. The FCC is considering calculating contribution obligations for interconnected VoIP providers based on either revenues or telephone numbers used by us. We cannot predict the outcome of this proceeding.

On June 8, 2007, the FCC released an order implementing various recommendations from its Independent Panel Reviewing the Impact of Hurricane Katrina on Communications Networks Panel, including a requirement that certain interconnected VoIP providers submit reports regarding the reliability and resiliency of their 911 systems. At this time, we are not subject to these reporting requirements but may become subject in future years.

On June 15, 2007, the FCC extended the disability access requirements of Sections 225 and 255 of the Communications Act, which applied to traditional phone services, to providers of interconnected VoIP services and to manufacturers of specially designed equipment used to provide those services. Section 255 of the Communications Act requires service providers to ensure that its equipment and service is accessible to and usable by individuals with disabilities, if readily achievable, including requiring service providers to ensure that information and documentation provided in connection with equipment or services be accessible to people with disabilities, where readily achievable and that employee training account for accessibility requirements. In addition, the FCC said that interconnected VoIP providers were subject to the requirements of Section 225, including contributing to the Telecommunications Relay Services, or TRS, fund and that they must offer 711 abbreviated dialing for access to relay services. At this time, we cannot predict the impact of these rules on our business or our ability to comply with these disability access obligations. We may be subject to enforcement actions including, but not limited to, fines, cease and desist orders, or other penalties if we are not able to comply with these new disability obligations. When the Order becomes effective, we will begin contributing to the federal TRS fund and we will likely pass those fees through to our customers increasing their bills for service. Moreover, compliance with the new disability rules may impose additional costs on the Company and reduce our profitability or cause us to increase the retail price for our services.

The effect of any future laws, regulations and the orders on our operations, including, but not limited to, the Packet8 service, cannot be determined. But as a general matter, increased regulation and the imposition of additional funding obligations increases our costs of providing service that may or may not be recoverable from our customers which could result in making our services less competitive with traditional telecommunications services if we increase our retail prices or decrease our profit margins if we attempt to absorb such costs.

Regulation of the Internet     

In addition to regulations addressing Internet telephony and broadband services, other regulatory issues relating to the Internet in general could affect our ability to provide our services. Congress has adopted legislation that regulates certain aspects of the Internet, including online content, user privacy, taxation, liability for third-party activities and jurisdiction. In addition, a number of initiatives pending in Congress and state legislatures would prohibit or restrict advertising or sale of certain products and services on the Internet, which may have the effect of raising the cost of doing business on the Internet generally.

10

Federal, state, local and foreign governmental organizations are considering other legislative and regulatory proposals that would regulate the Internet. We cannot predict whether new taxes will be imposed on our services, and depending on the type of taxes imposed, whether and how our services would be affected thereafter. Increased regulation of the Internet may decrease its growth and hinder technological development, which may negatively impact the cost of doing business via the Internet or otherwise materially adversely affect our business, financial condition and results of operations.

Our ability to compete depends, in part, on our ability to obtain and enforce intellectual property protection for our technology in the United States and internationally. We currently rely primarily on a combination of trade secrets, patents, copyrights, trademarks and licenses to protect our intellectually property. As of May 30, 2007, we had 68 United States patents that have been issued and additional United States and foreign patent applications pending. We do not consider any of the pending patents to be critical to our business. Our patents expire on dates ranging from 2012 to 2024. We cannot predict whether our pending patent applications will result in issued patents.

To protect our trade secrets and other proprietary information, we require our employees to sign agreements providing for the maintenance of confidentiality and also the assignment of rights to inventions made by them while in our employ. There can be no assurance that our means of protecting our proprietary rights in the United States or abroad will be adequate or that competition will not independently develop technologies that are similar or superior to our technology, duplicate our technology or design around any of our patents. In addition, the laws of foreign countries in which our products are or may be sold do not protect our intellectual property rights to the same extent as do the laws of the United States. Our failure to protect our proprietary information could cause our business and operating results to suffer.

We are also subject to the risks of adverse claims and litigation alleging infringement of the intellectual property rights of others, such claims and litigation could require us to expend substantial resources and distract key employees from their normal duties, which could have a material adverse effect on our operating results, cash flows and financial condition. The communications and software industries are subject to frequent litigation regarding patent and other intellectual property rights. Moreover, the VoIP service provider community is becoming increasingly a target of patent holders. There is a risk that we will be a target of assertions of patent rights and that we may be required to expend significant resources to investigate and defend against such assertions of patent rights.

We rely upon certain technology, including hardware and software, licensed from third parties. There can be no assurance that the technology licensed by us will continue to provide competitive features and functionality or that licenses for technology currently utilized by us or other technology which we may seek to license in the future will be available to us on commercially reasonable terms or at all. The loss of, or inability to maintain existing licenses could result in shipment delays or reductions until equivalent technology or suitable alternative products could be developed, identified, licensed and integrated, and could harm our business. These licenses are on standard commercial terms made generally available by the companies providing the licenses. To date, the cost and terms of these licenses individually has not been material to our business.

We have only one reportable segment. Financial information relating to our product lines and information on revenues generated in different geographic areas are set forth in Note 9 to our consolidated financial statements contained in Part II, Item 8 of this Report.

As of March 31, 2007, our workforce consisted of 160 employees and 35 contractors. None of our employees are represented by a labor union or are subject to a collective bargaining arrangement.

Our executive officers as of the date of this report are listed below.

If any of the following risks actually occur, our business, results of operations and financial condition could suffer significantly.

Our future success as a Company depends on our ability to significantly increase revenues generated from our Packet8 services. In turn, the success of our Packet8 voice and video communications services depends, among other things, upon future demand for VoIP telephony systems and services. Because the use of our service requires that the user be a subscriber to an existing broadband Internet service, most typically provided through a cable or digital subscriber line, or DSL, connection, slow or limited adoption of broadband Internet service could adversely affect the growth in our subscriber base and revenues. Although the number of broadband subscribers worldwide has grown significantly over the last five years, this service has not yet been adopted by a majority of consumers. To increase deployment of broadband Internet service providers of broadband Internet service, such as traditional telephone companies and cable companies must continue to invest in the deployment of high speed broadband networks to residential and business customers, developments over which we have no control. In addition, VoIP networks must improve quality of service for real-time communications, managing effects such as packet jitter, packet loss, and unreliable bandwidth, so that toll-quality service can be provided; VoIP telephony equipment and services must achieve a similar level of reliability that users of the PSTN have come to expect from their telephone service, and the cost and feature benefits of VoIP must be sufficient to cause customers to switch away from traditional telephony service providers. Furthermore, customers in markets serviced by deregulated telecommunications providers are not familiar with obtaining services from competitors of these providers and may be reluctant to use new providers, such as us. We will need to devote substantial resources to educate customers and end users about the benefits of VoIP telephony solutions in general and our services in particular. If any or all of these factors fail to occur, our business may be affected adversely.

It is not clear whether suppliers of broadband Internet access have a legal obligation to allow their customers to access and use our service without interference. As a result of recent decisions by the U.S. Supreme Court and the FCC, providers of broadband services are subject to relatively light regulation by the FCC. Consequently, federal and state regulators might not prohibit broadband providers from limiting their customers' access to VoIP or otherwise discriminating against VoIP providers. Conceivably, some providers of broadband access may take measures that affect their customers' ability to use our

12

service, such as degrading the quality of the data packets we transmit over their lines, giving those packets low priority, giving other packets higher priority than ours, blocking our packets entirely or attempting to charge their customers more for also using our services. Interference with our service or higher charges for also using our service could cause us to lose existing customers, impair our ability to attract new customers and harm our revenue and growth. These problems have arisen in international markets.

Certain aspects of our service are not the same as traditional telephone service. Because our continued growth is dependent on the adoption of our services by mainstream customers and business customers, our ability to adequately address significant differences through our technology, customer services, marketing and sales efforts is becoming increasingly important. For example:

• Our business services differ from traditional business private branch exchange, or PBX, systems in that no customer premise equipment is required other than our telephones and terminal adapters. There is no "equipment closet" or dedicated voice wiring that needs to be accomplished. For many of our customers, these are unfamiliar concepts.

• Our E911 calling service is different, in significant respects, from the E911 service associated with traditional wireline and wireless telephone providers.

• Our customers may experience higher dropped-call rates than they are used to from traditional wireline telephone carriers because our services depend on networks and services with more single points of failure than traditional wireline networks.

• Our customers cannot accept collect calls.

• In the event of a power loss or Internet access interruption, our services are interrupted. Unlike some cable VoIP services, we have not installed batteries at the customer premises to provide emergency power for our customers' equipment if they lose power, though our data centers are protected by power backup and other measures to mitigate the risk that we can maintain our data center operations in the event of a power outage or some other emergency situation.

If customers do not accept the differences between our service and traditional telephone service, they might not subscribe to our VoIP services and our business, operating results and cash flows would be affected adversely.

VoIP telephony is an emerging market that is characterized by rapid changes in customer requirements, frequent introductions of new and enhanced products, and continuing and rapid technological advancement. To compete successfully in this emerging market, we must continue to design, develop, manufacture, and sell new and enhanced VoIP telephony software products and services that provide increasingly higher levels of performance and reliability at lower cost. These new and enhanced products

13

must take advantage of technological advancements and changes, and respond to new customer requirements. Our success in designing, developing, manufacturing, and selling such products and services will depend on a variety of factors, including:

• the identification of new technologies and timely implementation of product design and development;
• the scalability of our VoIP telephony software products;
• product and feature selection;
• product performance;
• cost-effectiveness of current products and services and products under development;
• our ability to successfully implement service features mandated by federal and state law; and
• effectiveness of promotional efforts.

Decreasing telecommunications rates may diminish or eliminate the competitive pricing advantage of our services. Increased regulation and the imposition of additional regulatory funding obligations at the federal and state level could require us either to increase the retail price for our services, thus making us less competitive or absorb such costs, thus decreasing our profit margins. In fiscal 2007, we began to pass Universal Service and E911 fees and taxes onto our customers. International and domestic telecommunications rates have decreased significantly over the last few years in most of the markets in which we operate, and we anticipate these rates to continue to decline in all of the markets in which we do business or expect to do business. Users who select our services to take advantage of the current pricing differential between traditional telecommunications rates and our rates may switch to traditional telecommunications carriers if such pricing differentials diminish or disappear, and we will be unable to use such pricing differentials to attract new customers in the future. In addition, our ability to market our services to other service providers depends upon the existence of spreads between the rates offered by us and the rates offered by traditional telecommunications carriers, as well as a spread between the retail and wholesale rates charged by the carriers from which we obtain wholesale services. Continued rate decreases would require us to lower our rates to remain competitive and will reduce or possibly eliminate any gross profit from our services. Furthermore, if telecommunications rates continue to decline, we may lose subscribers for our services.

We leverage the infrastructure of third party network service providers to provide telephone numbers, PSTN call termination and origination services and local number portability for our customers rather than deploying our own network throughout the United States. This decision has resulted in lower operating costs for our business in the short term but has reduced our operating flexibility and ability to make timely service changes. If any of these network service providers cease operations or otherwise terminate the services that we depend on, the delay in switching our technology to another network service provider, if available, and qualifying this new service could have a material adverse effect on our business, operating results and cash flows.

While we believe that relations with our current service providers are good and we have contracts in place, there can be no assurance that these service providers will be able or willing to supply cost-effective services to us in the future or that we will be successful in signing up alternative or additional providers. While we believe that we could replace our current providers, if necessary, our ability to provide service to our subscribers would be impacted during this timeframe, and this could have an adverse effect on our business, financial condition or results of operations. The loss of access to, or requirement to change, the telephone numbers we provide to our customers also could have a material adverse effect on our business.

The telecommunications industry is highly competitive. We face intense competition from traditional telephone companies, wireless companies, cable companies, competitive local exchange carriers, alternative voice communication providers and independent VoIP providers.

14

Most traditional wireline and wireless telephone service providers and cable companies are substantially larger and better capitalized than we are and have the advantage of a large existing customer base. Because most of our target customers are already purchasing communications services from one or more of these providers, our success is dependent upon our ability to attract target customers away from their existing providers. Until recently, our target market has been composed largely of early adopters, or people who tend to seek out new technologies and services. Attracting customers away from their existing providers will become more difficult as the early adopter market becomes saturated and mainstream customers make up more of our target market. In addition, these competitors could focus their substantial financial resources to develop competing technology that may be more attractive to potential customers than what we offer. Our competitors' financial resources may allow them to offer services at prices below cost or even for free in order to maintain and gain market share or otherwise improve their competitive positions. Our competitors also could use their greater financial resources to offer VoIP services with more attractive service packages that include on-site installation and more robust customer service. In addition, because of the other services our competitors provide, they may choose to offer VoIP services as part of a bundle that includes other products, such as video, high speed Internet access and wireless telephone service, which we do not offer. This bundle may enable our competitors to offer VoIP service at prices with which we may not be able to compete or to offer functionality that integrates VoIP service with their other offerings, both of which may be more desirable to consumers. Any of these competitive factors could make it more difficult for us to attract and retain customers, cause us to lower our prices in order to compete and reduce our market share and revenues.

We also compete against established alternative voice communication providers and face competition from other large, well-capitalized Internet companies that have recently launched or plan to launch VoIP-enabled instant messaging services. In addition, we compete with independent VoIP service providers. Some of these service providers may choose to sacrifice revenue in order to gain market share and have offered their services at lower prices or for free. In order to compete with such service providers, we may have to significantly reduce our prices, which would delay or prevent our profitability.

We also are subject to the risk that new technologies may be developed that are able to deliver competing voice services at lower prices, better or more conveniently. Future competition from new technologies could have a material adverse effect on our growth and operating results.

Given the significant price competition in the markets for our products, we are at a significant disadvantage compared to our competitors, many of whom have substantially greater resources, and therefore may be better able to withstand an extended period of downward pricing pressure. The adverse impact of a shortfall in our revenues may be magnified by our inability to adjust spending to compensate for such shortfall. Announcements by our competitors or us of new products and technologies could cause customers to defer purchases of our existing products, which also could have a material adverse effect on our business and operating results.

Most of our current and potential competitors have longer operating histories, significantly greater resources and name recognition and a larger base of customers than we have. As a result, these competitors may have greater credibility with our existing and potential customers. They also may be able to adopt more aggressive pricing policies and devote greater resources to the development, promotion and sale of their products than we can to ours. Our competitors may also offer bundled service arrangements offering a more complete product despite the technical merits or advantages of our products. Competition could decrease our prices, reduce our sales, lower our gross profits or decrease our market share.

We also rely on third party component suppliers to provide semiconductor circuit packages for our products. In some instances, these components are provided by a single supplier. Our reliance on these suppliers involves a number of risks, including reduced control over delivery schedules, quality assurance and costs. We currently do not have long-term supply contracts with any of these component vendors. As a result, most of these third party vendors are not obligated to provide products or perform services to us for any specific period, in any specific quantities or at any specific price, except as may be

15

provided in a particular purchase order. The inability of these third party vendors to deliver components of acceptable quality and in a timely manner, particularly the sole source vendors, could adversely affect our operating results or cause them to fluctuate more than anticipated. Additionally, some of our products may require specialized or high-performance component parts that may not be available in quantities or in time frames that meet our requirements.

Our Packet8 service must successfully integrate with products from other vendors, such as gateways to traditional telephone systems. As a result, when problems occur in a network, it may be difficult to identify the source of the problem. The occurrence of hardware and software errors, whether caused by our Packet8 service or another vendor's products, may result in the delay or loss of market acceptance of our products and any necessary revisions may force us to incur significant expenses. The occurrence of some of these types of problems may seriously harm our business, financial condition or results of operations.

Certain technology necessary for us to provide our services may in fact be patented by other parties either now or in the future. If such technology were held under patent by another person, we would have to negotiate a license for the use of that certain technology. We may not be able to negotiate such a license at a price that is acceptable. The existence of such a patent, or our inability to negotiate a license for any such technology on acceptable terms, could force us to cease using such technology and offering products and services incorporating such technology.

We rely upon certain technology, including hardware and software, licensed from third parties. There can be no assurance that the technology licensed by us will continue to provide competitive features and functionality or that licenses for technology currently utilized by us or other technology which we may seek to license in the future will be available to us on commercially reasonable terms or at all. The loss of, or inability to maintain, existing licenses could result in shipment delays or reductions until equivalent technology or suitable alternative products could be developed, identified, licensed and integrated, and could harm our business. These licenses are on standard commercial terms made generally available by the companies providing the licenses. The cost and terms of these licenses individually are not material to our business.

We rely in part on trademark, copyright, and trade secret law to protect our intellectual property in the United States and abroad. We seek to protect our software, documentation, and other written materials under trade secret and copyright law, which afford only limited protection. We also rely in part on patent law to protect our intellectual property in the United States and internationally. As of May 30, 2007, we hold 68 United States patents and have additional United States and foreign patent applications pending. We cannot predict whether such pending patent applications will result in issued patents that effectively protect our intellectual property. We may not be able to protect our proprietary rights in the United States or internationally (where effective intellectual property protection may be unavailable or limited), and competitors may independently develop technologies that are similar or superior to our technology, duplicate our technology or design around any patent of ours. We have in the past licensed and in the future expect to continue licensing our technology to others many of whom are located or may be located abroad. There are no assurances that such licensees will protect our technology from misappropriation. Moreover, litigation may be necessary in the future to enforce our intellectual property rights, to determine the validity and scope of the proprietary rights of others, or to defend against claims of infringement or invalidity. Such litigation could result in substantial costs and diversion of management time and resources and could have a material adverse effect on our business, financial condition, and operating results. Any settlement or adverse determination in such litigation would also subject us to significant liability.

Our products must comply with industry standards, FCC regulations, state, local, country-specific and international regulations, and changes may require us to modify existing products and/or services.

In addition to reliability and quality standards, the market acceptance of telephony over broadband IP networks is dependent upon the adoption of industry standards so that products from multiple manufacturers are able to communicate with each other. Our VoIP telephony products rely heavily on communication standards such as SIP, MGCP and network standards such as TCP/IP and UDP to interoperate with other vendors' equipment. There is currently a lack of agreement among industry leaders about which standard should be used for a particular application, and about the definition of the standards themselves. These standards, as well as audio and video compression standards, continue to evolve. We also must comply with certain rules and regulations of the Federal Communications Commission (FCC) regarding electromagnetic radiation and safety standards established by Underwriters Laboratories, as well as similar regulations and standards applicable in other countries. Standards are continuously being modified and replaced. As standards evolve, we may be required to modify our existing products or develop and support new versions of our products. We must comply with certain federal, state and local requirements regarding how we interact with our customers, including marketing practices, consumer protection, privacy, and billing issues, the provision of 911 emergency service and the quality of service we provide to our customers. The failure of our products and services to comply, or delays in compliance, with various existing and evolving standards could delay or interrupt volume production of our VoIP telephony products, subject us to fines or other imposed penalties, or harm the perception and adoption rates of our service, any of which would have a material adverse effect on our business, financial condition or operating results.

Regulatory treatment of VoIP telephony outside the United States varies from country to country and often the laws are unclear. We currently distribute our products and services directly to consumers and through resellers that may be subject to telecommunications regulations in their home countries. The failure by us our customers and resellers to comply with these laws and regulations could reduce our revenue and profitability. Because of our relationship with the resellers, some countries may assert that we are required to register as a provider in that country. In such case, our failure to do so could subject us to fines or penalties. In addition, some countries are considering subjecting VoIP services to the regulations applied to traditional telephone companies. Regulatory developments such as these could have a material adverse effect on our international operation.

There are an increasing number of regulations and rulings that specifically address access to commerce and communications services on the Internet, including IP telephony. We are unable to predict the impact, if any, that future legislation, legal decisions or regulations concerning the Internet may have on our business, financial condition, and results of operations. Regulation may be targeted towards, among other things, assessing access or settlement charges, imposing taxes related to internet communications and imposing tariffs or regulations based on encryption concerns or the characteristics and quality of products and services, any of which could restrict our business or increase our cost of doing business. The increasing growth of the broadband IP telephony market and popularity of broadband IP telephony products and services heighten the risk that governments or other legislative bodies will seek to regulate broadband IP telephony and the Internet. In addition, large, established telecommunication companies may devote substantial lobbying efforts to influence the regulation of the broadband IP telephony market, which may be contrary to our interests.

There is risk that a regulatory agency requires us to conform to rules that are unsuitable for IP communications technologies or rules that cannot be complied with due to the nature and efficiencies of IP routing, or are unnecessary or unreasonable in light of the manner in which Packet8 offers service to its customers. It is not possible to separate the Internet, or any service offered over it, into intrastate and interstate components as we currently have no means to automatically identify the physical location of one of our subscribers on the Internet. While suitable alternatives may be developed in the future, the current IP network does not enable us to identify the geographic nature of the traffic traversing the Internet.

We may be subject to liabilities for past sales and additional taxes, surcharges and fees.

We have received inquiries or demands from numerous states and municipal taxing and 911 agencies seeking payment of taxes that are applied to or collected from the customers of providers of traditional public switched telephone network services. We have consistently maintained that these taxes do not apply to our service for a variety of reasons depending on the statute or rule that establishes such obligations. In September 2006, our largest third party network service provider vendor began passing through E911 taxes to us. On October 1, 2006, we began collecting certain state and local E911 charges from our customers for these amounts. The amounts collected from our customers are paid to the third party network service provider. We have not collected or accrued liabilities for E911 taxes prior to October 1, 2006, and it is possible that substantial claims for back taxes may be asserted against us, which could adversely affect our business financial condition or operating results.

One or more states or foreign countries may seek to impose sales, use or other tax collection obligations on us. We have received inquiries or demands from numerous state authorities and are currently under audit by one state. A successful assertion by one or more states or foreign countries that we should collect sales, use or other taxes on the sale of customer premise equipment or services could result in substantial tax liabilities for past sales, decrease our ability to compete with traditional telephone companies, and could have a material adverse effect on our business, financial condition or operating results. We have recorded an expense of $841,000 and $531,000 for years ended March 31, 2007 and 2006, respectively, as our estimate of the increase in probable tax exposure for such assessments. We believe that our exposure for assessments is $1,570,000 as of March 31, 2007, which is recorded as an other accrued liability in our condensed consolidated balance sheets.

Both our emergency calling service and our E911 calling service are different, in significant respects, from the emergency calling services offered by traditional wireline telephone companies. In each case, the differences may cause significant delays, or even failures, in callers' receipt of the emergency assistance they need.

Traditional wireline telephone companies route emergency calls over a dedicated infrastructure directly to an emergency services dispatcher at the Public Safety Answering Point, or PSAP, in the caller's area. Generally, the dispatcher automatically receives the caller's phone number and actual location information. While the E911 service we have deployed in the United States is designed to route calls in a fashion similar to traditional wireline services, our E911 capabilities are not yet available from all locations. In addition, the only location information that our E911 service can transmit to a dispatcher at a PSAP is the information that our customers have registered with us. A customer's registered location may be different from the customer's actual location at the time of the call because customers can use their Packet8 equipment to make calls almost anywhere a broadband connection is available.

We are currently deploying E911 service that is similar to the emergency calling services provided to customers of traditional wireline telephone companies in the same area. For those customers located in an E911 area, emergency calls are routed, subject to the limitations discussed below, directly to an emergency services dispatcher at the PSAP in the area of the customer's registered location. The dispatcher will have automatic access to the customer's telephone number and registered location information. If a customer moves their Packet8 service to a new location, the customer's registered location information must be updated and verified. Until that takes place, the customer will have to verbally advise the emergency dispatcher of his or her actual location at the time of an emergency 911 call.

The emergency calls of customers located in areas where we are currently unable to provide E911 service as described above are supported by a national call center that is run by a third-party provider and operates 24 hours per day, seven days a week.

18

These operators still receive the customer's registered service location and phone number automatically, and coordinate connecting the caller to the appropriate PSAP or emergency services provider and providing the customer's registered service location and phone number to those local authorities. In the event that a customer experiences a broadband or power outage, or if a network failure were to occur, the customer will not be able to reach an emergency services provider using our services.

Delays our customers encounter when making emergency services calls and any inability of the answering point to automatically recognize the caller's location or telephone number can result in life threatening consequences. Customers may in the future attempt to hold us responsible for any loss, damage, personal injury or death suffered as a result of any failure of our E911 services and, unlike traditional wireline and wireless telephone providers, there are no state or federal provisions that currently indemnify or limit the liability of VoIP services such as ours for connecting and carrying emergency 911 phone calls over IP networks.

In May 2005, the FCC unanimously adopted an order and Notice of Proposed Rulemaking, or NPRM, which required VoIP providers that interconnect with the PSTN, or interconnected VoIP providers, to provide enhanced 911, or E911, service.

The FCC may determine that our nomadic emergency calling solution does not satisfy the requirements of its VoIP E911 order because, in some instances, our nomadic emergency calling solution requires that we route an emergency call to a national emergency call center instead of connecting Packet8 subscribers directly to a local PSAP through a dedicated connection and through the appropriate selective router. The FCC may issue further guidance on compliance requirements in the future that might require us to disconnect those subscribers not receiving access to emergency services in a manner consistent with the VoIP E911 order. The effect of such disconnections, monetary penalties, cease and desist orders or other enforcement actions initiated by the FCC or other agency or task force against us could have a material adverse effect on our financial position, results of operations, cash flows or business reputation.

On August 5, 2005, the FCC unanimously adopted an order responsive to a joint petition filed by the Department of Justice, the Federal Bureau of Investigation, and the Drug Enforcement Administration asking the FCC to declare that broadband Internet access services and VoIP services be covered by the Communications Assistance for Law Enforcement Act, or CALEA.

The FCC, in a subsequent order released on May 12, 2006, required all interconnected VoIP providers to become fully CALEA compliant by May 14, 2007. The FCC allowed VoIP providers to comply with CALEA through the use of a solution provided by a trusted third party with the ability to extract call content and call-identifying information from a VoIP provider's network. While the FCC permits carriers to use the services provided these third parties to become CALEA compliant by the deadline, the carrier remains ultimately responsible for ensuring the timely delivery of call content and call-identifying information to law enforcement, and for protecting subscriber privacy, as required by CALEA.

19

On April 2, 2007, the FCC released an order extending the application of the customer proprietary network information, or CPNI, rules to interconnected VoIP providers. VoIP providers have six months from the effective date of the order to implement all the CPNI rules. CPNI includes information such as the phone numbers called by a consumer; the frequency, duration, and timing of such calls; and any services/features purchased by the consumer, such as call waiting, call forwarding, and caller ID, in addition to other information that may appear on a consumer's bill.

Under the FCC's existing rules, carriers may not use CPNI without customer approval except in narrow circumstances related to their provision of existing services, and must comply with detailed customer approval processes when using CPNI outside of these narrow circumstances. The new CPNI requirements are aimed at establishing more stringent security measures for access to a customer's CPNI data in the form of enhanced passwords for on-line access and call-in access to account information as well as customer notification of account or password changes.

At the present time we do not utilize our customer's CPNI in a manner which would require us to obtain consent from our customers, but in the event that we do in the future, we will be required to adhere to specific CPNI rules aimed at marketing such services. By December 8, 2007, we will be required to implement internal processes in order to be in compliance with all of the FCC's CPNI rules. Our failure to achieve compliance with any future CPNI orders, rules, filings or standards, or any enforcement action initiated by the FCC or other agency, state or task force against us could have a material adverse effect on our financial position, results of operations or cash flows.

20

We charge our subscribers a USF fee equal to the USF contribution amounts we must contribute based upon our subscribers' retail revenues. The impact of this price increase on our customers or our inability to recoup our costs or liabilities in remitting USF contributions or other factors could have a material adverse effect on our financial position, results of operations and cash flows.

On May 31, 2007, the FCC extended the disability access requirements of Sections 225 and 255 of the Communications Act, which applied to traditional phone services, to providers of interconnected VoIP services and to manufacturers of specially designed equipment used to provide those services. Section 255 of the Communications Act requires service providers to ensure that its equipment and service is accessible to and usable by individuals with disabilities, if readily achievable, including requiring service providers to ensure that information and documentation provided in connection with equipment or services be accessible to people with disabilities, where readily achievable and that employee training account for accessibility requirements. In addition, the FCC said that interconnected VoIP providers were subject to the requirements of Section 225, including contributing to the Telecommunications Relay Services, or TRS, fund and that they must offer 711 abbreviated dialing for access to relay services. At this time, until the formal release of the FCC order, we cannot predict the impact of these obligations on our business or our ability to comply with these disability obligations. We will likely pass these additional costs on to our customers and the impact of this price increase or our inability to recoup our costs or liabilities or other factors could have a material adverse effect on our financial position, results of operations and cash flows. We may be subject to enforcement actions including, but not limited to, fines, cease and desist orders, or other penalties if we are not able to comply with these new disability requirements.

The Federal Communications Commission, or FCC, and various state commissions are considering the imposition of additional fees on interconnected VoIP providers, like us. The FCC is currently considering subjecting interconnected VoIP providers to regulatory fee recovery obligations. Several states are either considering extending or have imposed state USF, state TRS fees, and other taxes and fees on interconnected VoIP providers like us. If we pass through the taxes, fees and surcharges that may be applied to our service, the impact of this price increase on our customers or our inability to recoup our costs or liabilities in remitting such taxes, fees and surcharges could have a material adverse effect on our financial position, results of operations and cash flows.

We support local number portability, or LNP, for our customers, which allow our customers to retain their existing telephone numbers when subscribing to our services. Transferring numbers is a manual process that in the past has taken us 20 business days or longer, although we have taken steps to automate this process to reduce the delay. A new customer of our services must maintain both the new Packet8 service and the customer's existing telephone service during the number transfer process. By comparison, transferring wireless telephone numbers among wireless service providers generally takes several hours, and transferring wireline telephone numbers among traditional wireline service providers generally takes a few days. The additional delay that we experience is due to our reliance on third party carriers to transfer the numbers, as well as the delay the existing telephone service provider may contribute to the process. Local number portability is considered an important feature by many potential customers, especially our business customers, and if we fail to reduce related delays, we may experience increased difficulty in acquiring new customers or retaining existing customers.

A fundamental requirement for operating an internet-based, worldwide voice and video communications service and electronically billing our Packet8 customers is the secure transmission of confidential information and media over public networks. Although we have developed systems and processes that are designed to protect consumer information and prevent fraudulent credit card transactions and other security breaches, failure to mitigate such fraud or breaches may adversely affect our operating results. The law relating to the liability of providers of online payment services is currently unsettled. We rely on third party providers to process and guarantee payments made by Packet8 subscribers up to certain limits, and we may be

21

unable to prevent our customers from fraudulently receiving goods and services. Our liability risk will increase if a larger fraction of our Packet8 transactions involve fraudulent or disputed credit card transactions. Any costs we incur as a result of fraudulent or disputed transactions could harm our business. In addition, the functionality of our current billing system relies on certain third-party vendors delivering services. If these vendors are unable or unwilling to provide services, we will not be able to charge for our Packet8 services in a timely or scalable fashion, which could significantly decrease our revenue and have a material adverse effect on our business, financial condition and operating results.

Subscribers have obtained access to the Packet8 service without paying for monthly service and international toll calls by unlawfully using our authorization codes and submitting fraudulent credit card information. To date, such losses from unauthorized credit card transactions and theft of service have not been significant. We have implemented anti-fraud procedures in order to control losses relating to these practices, but these procedures may not be adequate to effectively limit all of our exposure in the future from fraud. If our procedures are not effective, consumer fraud and theft of service could significantly decrease our revenue and have a material adverse effect on our business, financial condition and operating results.

Our rate of customer terminations, or average monthly customer churn, was 4.2% for the year ended March 31, 2007. Our churn rate could increase in the future if customers are not satisfied with our service. Other factors, including increased competition from other providers, also influence our churn rate.

Because of churn, we have to acquire new customers on an ongoing basis just to maintain our existing level of customers and revenues. As a result, marketing expense is an ongoing requirement of our business. If our churn rate increases, we will have to acquire even more new customers in order to maintain our existing revenues. We incur significant costs to acquire new customers, and those costs are an important factor in determining our net losses and achieving future profitability. Therefore, if we are unsuccessful in retaining customers or are required to spend significant amounts to acquire new customers beyond those budgeted, our revenue could decrease and our net losses could increase.

We currently sell our products direct to consumers and through resellers, and are focusing efforts on diversifying and increasing our distribution channels. Our future revenue growth will depend in large part on sales of our products through reseller and other distribution relationships. We may not be successful in developing additional distribution relationships. Agreements with distribution partners generally provide for one-time and recurring commissions based on our list prices, and do not require minimum purchases or restrict development or distribution of competitive products. Therefore, entities that distribute our products may compete with us. In addition, distributors and resellers may not dedicate sufficient resources or give sufficient priority to selling our products. Our failure to develop new distribution channels, the loss of a distribution relationship or a decline in the efforts of a material reseller or distributor could have a material adverse effect on our business, financial condition or results of operations.

• changes in market demand;
• the timing of customer orders;
• customer cancellations;
• competitive market conditions;
• lengthy sales cycles and/or regulatory approval cycles;
• new product introductions by us or our competitors;

22

• market acceptance of new or existing products;
• the cost and availability of components;
• the mix of our customer base and sales channels;
• the mix of products sold;
• the management of inventory;
• continued compliance with industry standards and regulatory requirements; and
• general economic conditions.

Due to these and other factors, we believe that period-to-period comparisons of our results of operations are not meaningful and should not be relied upon as indicators of our future performance. It is possible that in some future periods our results of operations may be below the expectations of public market analysts and investors. If this were to occur, the price of our common stock would likely decline significantly.

The development and marketing of our VoIP products will continue to place a significant strain on our limited personnel, management, and other resources. Our future success depends upon the continued services of our executive officers and other key employees who have critical industry experience and relationships that we rely on to implement our business plan. None of our officers or key employees are bound by employment agreements for any specific term. The loss of the services of any of our officers or key employees could delay the development and introduction of, and negatively impact our ability to sell our products which could adversely affect our financial results and impair our growth. We currently do not maintain key person life insurance policies on any of our employees.

Our products have lead times of up to several months, and are built to forecasts that are necessarily imprecise. Because of our practice of building our products to necessarily imprecise forecasts, it is likely that, from time to time, we will have either excess or insufficient product inventory. In addition, because we rely on third party vendors for the supply of components and contract manufacturers to assemble our products, our inventory levels are subject to the conditions regarding the timing of purchase orders and delivery dates that are not within our control. Excess inventory levels would subject us to the risk of inventory obsolescence, while insufficient levels of inventory may negatively affect relations with customers. For instance, our customers rely upon our ability to meet committed delivery dates, and any disruption in the supply of our products could result in legal action from our customers, loss of customers or harm to our ability to attract new customers. Any of these factors could have a material adverse effect on our business, operating results or financial condition.

Pursuant to Emerging Issues Task Force Issue No. 00-19, "Accounting for Derivative Financial Instruments Indexed to and Potentially Settled in a Company's Own Stock" ("EITF 00-19"), warrants issued to three investors in three different equity financings we consummated in fiscal 2005 and 2006 are classified as liabilities because the possibility, however likely or unlikely, that the Company would be unable to deliver registered shares upon a future exercise of these warrants means that the warrants are deemed to include a "net cash settlement" provision within the meaning of EITF 00-19. The required accounting for a warrant with a "net cash settlement" provision under EITF 00-19 is to estimate the fair value on the date of issuance and to record a liability equal to that value to reflect the required assumption that the Company will breach its obligation to deliver registered shares in the future (which we refer to as a "presumed breach"). The warrants will continue to be recorded as liabilities until such time as the warrants are exercised, expire or we and the warrant holders amend the applicable warrant agreement in a manner that renders this accounting treatment unnecessary. In the event that at the end of any fiscal quarter the fair value of these warrants increases or decreases, we will be required to re-value the warrants and reflect such change for the applicable fiscal quarter in our financial statements in accordance with EITF 00-19. If the fair value at the end of any fiscal quarter increases, we will recognize a corresponding increase in expense for such fiscal quarter, as well as reflect a

23

corresponding increase in our liabilities for such fiscal quarter, in accordance with EITF 00-19, resulting in a reduction of our stockholders' equity on our balance sheet for such fiscal quarter and a decrease in net income on our income statement for such fiscal quarter. If the fair value at the end of any fiscal quarter decreases, we will recognize a corresponding decrease in expense for such fiscal quarter, as well as reflect a corresponding decrease in our liabilities for such fiscal quarter, in accordance with EITF 00-19, resulting in an increase of our stockholders' equity on our balance sheet for such fiscal quarter and increase in net income on our income statement for such fiscal quarter. The amount we record as a liability under EITF 00-19 is not, nor do we intend for it to be an admission or stipulation of the amount that we would owe or be obligated to pay the warrant holder in the event of an actual breach by us of the warrant terms. In fact, we have made no determination of the amount of liability, if any, that we would owe to the warrant holder in the event of such a breach.

As of March 31, 2007, we had cash and cash equivalents and investments of approximately $11.9 million. Unless we achieve and maintain profitability in the future, we will need to raise additional capital. We may not be able to obtain such additional financing as needed on acceptable terms, or at all, which may require us to reduce our operating costs and other expenditures, including reductions of personnel and capital expenditures. If we issue additional equity or convertible debt securities to raise funds, the ownership percentage of our existing stockholders would be reduced and they may experience significant dilution. New investors may demand rights, preferences or privileges senior to those of existing holders of our common stock. If we are not successful in these actions, we may be forced to cease operations.
