Dear H.323 Software Licensee:

As you know, we are now in the process of planning programs to support, promote and grow the Users' Group into a leading-edge, proactive fellowship that helps to advance both the technology and the marketplace. Our objective is to provide a convenient forum for RADVision customers/partners (that's you) to discuss opportunities and issues they encounter when building standards-compliant, interoperable, high-value H.323 products.

WE WANT YOUR SUGGESTIONS AND FEEDBACK -- PLEASE FILL OUT OUR USER GROUP SURVEY! The survey asks you what you think the top objectives/goals of the user group should be, what topics you would like to discuss on a quarterly basis with RADVision experts, how frequently you think user group meetings should be held, what you think are the most valuable topics to cover in user group communiques, and more.

You will find the survey at http://207.201.151.179/support/. It will take you approximately 10 minutes to fill out. You can submit it online or print it out and fax it back to us (201.529.3516) - which ever way you are most comfortable with. If you don't have Internet access, just give us a call at 201-529-4300, extension 246 or e-mail us at dorothy@radvision.com and we will be more than happy to send it or e-mail it to you right away.

We look forward to meeting and working closely with you. If you have any questions whatsoever, please do not hesitate to contact me.

Sincerely,

Dorothy Nicholson Director of Marketing RADVision, Inc. Tel. 201.529.4300 x246 Fax: 201-529.3516 E-mail: dorothy@radvision.com
