Enabling a Directory Number to be Watched
To enable a line associated with a directory number to be monitored by a phone registered to a
Cisco Unified CME router, perform the following steps. The line is enabled as a presentity and phones
can subscribe to its line status through the BLF call-list and BLF speed-dial features. There is no
restriction on the type of phone that can have its lines monitored; any line on any IP phone or on an
analog phone on supported voice gateways can be a presentity.
Restrictions
• A presentity is identified by a directory number only.
• BLF monitoring indicates the line status only.
Step 4
presence enable
Example:
Router(config-sip-ua)# presence enable

Step 5
exit
Example:
Router(config-sip-ua)# exit

Step 6
presence
Example:

the “Enabling a SCCP Phone to Monitor BLF Status for
Speed-Dials and Call Lists” section on page 891.
