The following line states display through BLF indicators on the phone:

•Line is idle—Displays when this line is not being used.

•Line is in-use—Displays when the line is in the ringing state and when a user is on the line, whether or not this line can accept a new call.

•BLF indicator unknown—Phone is unregistered or this line is not allowed to be watched.

Cisco Unified CME acts as a presence agent for internal lines (both SIP and SCCP) and as a presence server for external watchers connected through a SIP trunk, providing the following functionality:

•Processes SUBSCRIBE requests from internal lines to internal lines. Notifies internal subscribers of any status change.

•Processes incoming SUBSCRIBE requests from a SIP trunk for internal SCCP and SIP lines. Notifies external subscribers of any status change.

•Sends SUBSCRIBE requests to external presentities on behalf of internal lines. Relays status responses to internal lines.

Presence subscription requests from SIP trunks can be authenticated and authorized. Local subscription requests cannot be authenticated.

For configuration information, see the “How to Configure Presence Service” section on page 887.
