Configuring and Verifying Basic Presence in CME
Cisco Communications Manager Express (CME) provides the ability for presence capabilities, permitting users to monitor the busy status of other local users. Presence allows users to subscribe to change in the line status of phones in the Cisco Unified CME system. This article walks through configuring the CME system with a single presence subscription, and details the steps for verification.
In CME, configuring presence requires:
- Enabling presence globally
- Allowing a DN to be monitored (watched)
- Configuring a busy-lamp speed dial on watcher's phone
- (Optionally) Allowing monitoring from the call lists (corporate directory, missed calls, etc.)
The minimum configuration required to configure basic Presence is as follows.
presence
allow subscribe
!
ephone-dn 1 octo-line
number 7001
allow watch
!
ephone 4
blf-speed-dial 1 7001 label "IT 7001"
!
Verify presence is enabled globally with the command show presence global:
CME#sh presence global
