Polycom VSX Series manual Integration with Microsoft Live Communications Server LCS

Configuring Network Use

Points to note about SIP:

The SIP protocol has been widely adapted for voice over IP communications and basic video conferencing; however, many of the advanced video conferencing capabilities are not yet standardized. Many capabilities also depend on the SIP server.

Examples of features that are not supported using SIP are:

•Polycom Video and Audio Error Concealment

•Encryption

•People and Content (H.239 and Polycom People+Content)

•H.263 Pro-Motion

Integration with Microsoft Live Communications Server (LCS)

Integration with Microsoft LCS allows you to set up a list of LCS contacts, see if the contacts are online, and call them without knowing or remembering their addresses. Contacts appear in the directory and can also be displayed on the home screen. For more information about the contact list home screen, refer to Displaying Contacts on the Home Screen on page 4-50.

2.Go to System > Admin Settings > Network > Call Preferences.

3.Select Enable SIP.

4.Go to System > Admin Settings > Network > IP > SIP Settings.
