Your video address is like your phone number—when someone wants to have a video call with you, he or she contacts you using your video address. For Jabber Video users, your video address is your Jabber Video username, followed by @jabber.com (it looks like an email address). If you are making a video call to another Cisco WebEx Telepresence user, the video address is typically in the format [display name]@webex.com .
See How do I find my Cisco Jabber Video for TelePresence video address? for information on locating your video address.
