RADVISION Reports Strong Second Quarter 2006 Results

Thursday July 27, 8:00 am ET

Revenues Reach $22.0 Million

Diluted EPS is $0.14

FAIR LAWN, N.J.--(BUSINESS WIRE)--July 27, 2006--RADVISION(R) (NASDAQ: RVSN -
News) today announced that revenues for the second quarter of 2006 reached a
record $22.0 million, representing a 26% increase from $17.5 million reported in
the second quarter of 2005.

Operating income for the second quarter of 2006 was $2.1 million. Excluding the
effect of stock-based compensation expense related to the adoption of FAS123R,
the Company achieved operating income of $3.3 million. This compares with
operating income of $2.2 million in the second quarter of 2005.

Net income for the 2006 second quarter was $3.2 million, or $0.14 per diluted
share. Excluding the effect of stock-based compensation expense, net income was
$4.4 million or $0.20 per diluted share. This compares with $2.9 million or
$0.13 per diluted share reported in the 2005 second quarter.

The Company had forecast that 2006 second quarter revenues would approximate
$21.5 million and that net income would approximate $3.1 million or $0.14 per
diluted share including stock-based compensation expense related to the adoption
of FAS123R. Excluding this item, the Company expected second quarter 2006 net
income to be $4.3 million or $0.19 per diluted share.

Business unit revenues for the second quarter of 2006 consisted of $16.0 million
in Networking Business Unit (NBU) sales and $6.0 million in Technology Business
Unit (TBU) sales, representing increases of 35% and 7%, respectively, over the
second quarter of 2005. NBU revenues exceeded the Company's forecast and TBU
revenues were in line with it.

For the first six months of 2006, revenues were $42.1 million, operating income
was $4.0 million and net income was $6.1 million or $0.27 per diluted share.
Excluding the effect of stock-based compensation expense, operating income for
the first six months of 2006 was $6.3 million and net income was $8.4 million or
$0.37 per diluted share. For the first half of 2005, revenues were $33.8
million, operating income was $4.1 million and net income was $5.4 million or
$0.24 per diluted share.

The Company ended the second quarter of 2006 with approximately $138.5 million
in cash and liquid investments, an increase of $2.8 million from March 31, 2006,
and equivalent to $6.23 per basic share. The increase reflects cash flow from
operations of $2.7 million and income of $541,000 from the exercise of options,
offset by $461,000 in capital expenditures.

Boaz Raviv, Chief Executive Officer, commented: "Our main growth driver in the
second quarter was the successful worldwide launch of our new SCOPIA(TM) v.5
platform and iView management application, which contributed to a 33% increase
in our room conferencing revenues over the second quarter of 2005 and a 60%
increase sequentially. We shipped SCOPIA v.5 for the largest phase of the
Defense Information Systems Agency (DISA) DVS-II project that we won with Cisco
and Northrop Grumman late last year. Our second quarter DISA sales were made
through Cisco, our largest channel partner. Total Cisco revenues rose 70%
year-over-year. Our non-Cisco channel sales in the Americas also were strong in
the quarter.







"Revenues from our Click to Meet(R) desktop solution were double those of the
2005 second quarter but were lower than the first quarter mainly because certain
budgets for new Federal projects were held back. However, our second quarter
included another sale for BVTC, or Battlefield Video Conferencing, which is
deployed by the U.S. Army for real-time war applications. Click to Meet is an
essential part of our broad strategy for unified communications. We recently
announced that Click to Meet supports Microsoft's RTVideo advanced video codec
as well as demonstrated its High Definition capabilities, as we continue to
develop first-to-market advances. We expect Click to Meet sales to resume
sequential growth in the third quarter.

"3G revenues rose 11% from the second quarter of 2005 reflecting sales to mobile
operators and applications service providers both in EMEA and Asia Pacific but
were below the record level achieved in the first quarter. Our 3G revenues
continue to fluctuate because 3G video is mainly in the trial and pilot phase.

"Our TBU revenues grew 7% from the second quarter of 2005. That growth included
strong sales of licenses for our SIP and SIP Server toolkits. We recently
announced the availability of an IMS-compliant SIP Toolkit, the first in what
will become a comprehensive portfolio of IMS development products. They also
included license sales of our 3G-324 toolkits along with related sales in
professional services and of our 324M ProLab(TM) testing tool. Earlier this week
we reported that Quanta Computer, one of China's leading developers of
computers, storage devices and displays, will use our 3G-324 Toolkit and testing
tool to develop a video-enabled 3G mobile handset based on Windows Mobile 5.0
operating system and running on an Intel application chip and Qualcomm baseband
chip."

Mr. Raviv concluded: "Our growth in the second quarter reflected our focus on
execution and the advancement of our technology leadership. We will continue to
pursue our strategy of enabling and advancing unified communications."

Guidance

The following statements are forward-looking, and actual results may differ
materially.

The Company expects revenues for the third quarter of 2006 to be approximately
$23.2 million and net income to approximate $3.4 million or $0.15 per diluted
share. This includes stock-based compensation expense related to the adoption of
FAS123R of $1.3 million or $0.06 per diluted share. Excluding this item, third
quarter 2006 net income is expected to be $4.7 million or $0.21 per diluted
share. That compares to third quarter 2005 revenues of $19.1 million and net
income of $4.0 million or $0.18 per diluted share. (Full details are available

(1) To supplement our consolidated financial statements presented in accordance
    with generally accepted accounting principles (GAAP), we use non GAAP
    measures of operating results, net income and earnings per share, which are
    adjusted from results based on GAAP to exclude the expenses we recorded for
    stock compensation in accordance with SFAS 123R. These non GAAP financial
    measures are provided to enhance overall understanding of our current
    financial performance and our prospects for the future. Specifically, we
    believe the non GAAP results provide useful information to both management,
    and investors as these non GAAP results exclude the expenses we recorded for
    stock compensation in accordance with SFAS 123R that we believe are not
    indicative of our core operating results. Further, these non GAAP results
    are one of the primary indicators management uses for assessing our
    performance, allocating resources and planning and forecasting future
    periods. These measures should be considered in addition to results prepared
    in accordance with GAAP, but should not be considered a substitute for or
    superior to GAAP results. These Non GAAP measures may be different than the
    non GAAP measures used by other companies.

(1) To supplement our consolidated financial statements presented in accordance
    with generally accepted accounting principles (GAAP), we use non GAAP
    measures of operating results, net income and earnings per share, which are
    adjusted from results based on GAAP to exclude the expenses we recorded for
    stock compensation in accordance with SFAS 123R. These non GAAP financial
    measures are provided to enhance overall understanding of our current
    financial performance and our prospects for the future. Specifically, we
    believe the non GAAP results provide useful information to both management,
    and investors as these non GAAP results exclude the expenses we recorded for
    stock compensation in accordance with SFAS 123R that we believe are not
    indicative of our core operating results. Further, these non GAAP results
    are one of the primary indicators management uses for assessing our
    performance, allocating resources and planning and forecasting future
    periods. These measures should be considered in addition to results prepared
    in accordance with GAAP, but should not be considered a substitute for or
    superior to GAAP results. These Non GAAP measures may be different than the
    non GAAP measures used by other companies.
