RADVISION Reports Record Results for Fourth Quarter and Full Year 2005

Wednesday February 8, 7:00 am ET

Fourth Quarter Revenues of $21.2 million and EPS of $0.24 Exceed Forecast
FAIR LAWN, N.J.--(BUSINESS WIRE)--Feb. 8, 2006--RADVISION (Nasdaq: RVSN - News)
today announced that revenues for the fourth quarter of 2005 reached a record
$21.2 million. This was a 21% increase from the fourth quarter of 2004 and
$670,000 above the Company's forecast for the quarter.

Operating income for the fourth quarter of 2005 rose 89% from the fourth quarter
of 2004 to $4.2 million.

Net income for the 2005 fourth quarter nearly doubled to a record $5.4 million,
or $0.24 per diluted share, compared with $2.8 million or $0.13 per diluted
share reported in the 2004 fourth quarter. The Company had forecast that 2005
fourth quarter net income would be $4.5 million or $0.20 per diluted share.

Business Unit revenues for the fourth quarter of 2005 consisted of $15.2 million
in Networking Business Unit (NBU) sales and $6.0 million in Technology Business
Unit (TBU) sales, representing increases of 27% and 8%, respectively, over the
fourth quarter of 2004.

For full year 2005, revenues were $74.0 million, operating income was $11.5
million and net income was $14.7 million or $0.66 per diluted share. For 2004,
revenues were $64.2 million, operating income was $4.1 million and net income
was $6.0 million or $0.28 per diluted share.

The Company ended the fourth quarter of 2005 with approximately $125.0 million
in cash and liquid investments, an increase of $9.2 million over the 2005 third
quarter, and equivalent to $5.80 per basic share. The increase reflects cash
flow of $5.8 million from operations and income of $3.8 million from the
exercise of options, offset by $400,000 in capital expenditures.

Boaz Raviv, Chief Executive Officer, commented: "Strong growth of our NBU
supported by better than forecasted TBU revenues were the principal drivers of
our record fourth quarter results."

"Our NBU benefited from sales to the Federal market of our desktop software
solution, Click to Meet(TM), as well as from initial sales of Click to Meet for
Microsoft Live Meeting. We also had record revenues from our channel partner
Cisco in the fourth quarter, which included $1 million related to the Defense
Information Systems Agency (DISA) contract. As previously reported, we expect to
receive a total of $6 to $8 million from this important contract. Our revenues
from Aethra demonstrated strong growth in the fourth quarter as well and they
have become our second largest customer.

"We saw strong growth in our 3G revenues in the fourth quarter, with a total of
six new deals with Service Providers in the Asia Pacific and EMEA regions,
mainly for new 3G video applications they are developing such as video mail to
offer to consumers. One of those will use Click to Meet for a commercial service
based on 3G.

"Our TBU achieved better than expected performance in the fourth quarter
reflecting very strong growth in royalties and increased maintenance fee
revenues. Revenues from licenses improved from the third quarter and rose 15%
year over year. We continued to see strong demand for our SIP and SIP server
toolkits as well as for our 3G-324M toolkits and testing tools. We also moved
forward in supporting the IP Multimedia Subsystem (IMS), which is a new
architecture supporting multimedia services for 3G and cable networks, to build
upon the technology leadership of our TBU.

Mr. Raviv concluded: "Our strong performance in the fourth quarter led to a
record year for RADVISION. We expect to achieve further growth in 2006 as video
conferencing continues to expand beyond the meeting room and reaches the
applications we touch every day."







Guidance

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

The Company expects revenues for the first quarter 2006 to be approximately
$20.0 million and net income to approximate $2.1 million or $0.09 per diluted
share. This includes stock-based compensation expense related to the adoption of
FAS123(R) of $1.2 million or $0.05 per diluted share and tax expense of $300,000
or $0.01 per diluted share. Before these items, first quarter 2006 net income is
expected to be $3.6 million or $0.15 per diluted share. This compares to first
quarter 2005 revenues of $16.3 million and net income of $2.4 million or $0.11
per diluted share. (Full details are available on the Company's web site at
