Enabling a Directory Number to be WatchedTo 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.
