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.
To configure a VSX system for use with Microsoft LCS:
1. Contact the LCS administrator to make sure that the VSX system has a
user account on the LCS server. Make a note of the account information.
2. Go to System > Admin Settings > Network > Call Preferences.
3. Select Enable SIP.
4. Go to System > Admin Settings > Network > IP > SIP Settings.
5. Configure these settings:
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
