Nortel Touts New VoIP Technology: Page 2 of 2

Also at the conference, Nortel demonstrated new features that will be available in version 3.0 of its Multimedia Communication Server 5100, which is slated to make its debut later this year. The platform provides multimedia, communications and collaboration applications to Nortel IP telephony users.

The new version includes dynamic presence capabilities, which automatically update users' availability status. For example, the system would automatically show that users are on the phone as soon as they pick up their handsets, without requiring them to change their status manually. Other new features include private chat rooms and point-to-multipoint video capabilities. The new system also scales down to 50 users, compared with 100 in the current version. All of the new features are based on Session Initiation Protocol (SIP), an emerging call-control standard.
