Thursday November 10, 7:00 am ET

 Boaz Raviv Named Chief Executive Officer Effective January 1

Five-Year Company Veteran with Extensive  Industry  Experience Now Heads TBU and
NBU

FAIR LAWN, N.J.--(BUSINESS WIRE)--Nov. 10, 2005--RADVISION (Nasdaq: RVSN - News)
today announced that Boaz Raviv, 45, currently General Manager overseeing both
of the Company's business units, has been chosen by the Board of Directors to
succeed Gadi Tamari as Chief Executive Officer effective January 1, 2006. Mr.
Tamari, who successfully built the Company over his four year tenure, has
submitted his resignation as CEO and as a member of the Board of Directors
effective December 31, 2005 to pursue new opportunities.

Boaz Raviv joined RADVISION in 2000 as General Manager of the Company's
Technology Business Unit (TBU). He assumed added responsibility for the
Company's Networking Business Unit (NBU) in mid-2004.

Prior to joining RADVISION, Mr. Raviv was Vice President of Business Development
and Marketing focusing on e-business products and solutions for Elron TeleSoft,
a leading provider of revenue and business assurance solutions for mobile,
fixed, 3G and IP telephony networks employed by leading Carrier Networks
worldwide. He also served as a Telecom Division Manager at Elron. Mr. Raviv
began his career at CAP GEMINI, France, a global leader in consulting,
technology, outsourcing and local professional services, where he spent eight
years in various key positions, including the development of the data
communications network.

Mr. Raviv holds a B.S. from the Technion, Israel's Institute of Technology in
Haifa. He served his apprenticeship at Robotic in CEMAGREF, the French National
Center of Mechanical Engineering, renowned for research and development in the
field of integrated equipment.

Zohar Zisapel, Chairman, stated: "Boaz Raviv has proven himself to be a highly
effective manager and leader during his five years at RADVISION. His depth of
knowledge about our technology, our market and our Company is invaluable. We are
confident that he is the right person to take the vision for this Company, which
Gadi Tamari played a central role in shaping, to the next level of realization."

Mr. Zisapel continued: "On behalf of the Board of Directors, I would like to
thank Gadi Tamari for the enormous contribution he has made as CEO of this
Company for the past four years. His insight into the development of our market
and the most effective way to position RADVISION within it has become reality.
We regrettably must accept his decision and we wish him well in his future
endeavors."

Gadi Tamari commented: "After four rewarding years at RADVISION, it is time for
me to move on and embark on a new challenge. This is an opportune time for my
decision because of the very strong Company that RADVISION is today. I am proud
of my accomplishments and the growth we have achieved. RADVISION today is nearly
twice the size it was when I arrived. I am leaving this Company in the hands of
a truly talented successor, a strong management team and a committed Board of
Directors. My best wishes go to Boaz Raviv and to everyone at RADVISION."

Boaz Raviv commented: "I am honored and pleased to take this next step in my
career at RADVISION. We are a company that is just beginning to realize the
enormous opportunity and potential I recognized when I first arrived. I
enthusiastically accept the responsibility to take this Company to the next
level of success and growth."
