For more details about the Interactions and Restrictions, please follow the Features and Services Guide pertinent to you Callmanager version:

This feature doesn't provide a voice message broadcating capability (sometimes called paging).
Note: Generally, on Call Manager 4.x the Intercoms were configured with a speeddial on the Admin phone set to ringdown
to the auto answer DN on the Manager phone. On CUCM 6.X and above it would be a speeddial to a number for example lets
Managers Number be 1000 then on the Admin's Phone add a DN 1000 with auto answer for the manager.
For more details refer Intercom
Cisco CallManager does not have a dedicated intercom feature. However, you can use the Auto Answer feature in Cisco CallManager. Activatving this option or button causes the speaker phone to go off hook automatically when an incoming call is received.
To configure Auto Answer, perform these steps:
For more information refer to Cisco IP Phone Configuration.
Many sites with an existing PBX also have a paging system, allowing users to call an extension on the PBX that forwards the audio broadcast to overhead loudspeakers. This concept is useful in workshops, parking lots, and open plan areas where a called party is not near a telephone handset. PBX manufacturers may provide dedicated line cards that interface with external paging amplifiers.
The Cisco CallManager needs the Cisco 2610 router to be configured as an H.323 gateway device. The extension number for the paging port is defined under the Cisco CallManager Route Pattern configuration page, pointing to the Cisco 2610 H.323 gateway.
When the number for the paging system is dialed, a VoIP call is made between the IP handset to the E&M port on the gateway router. The voice port goes off hook. This is indicated by the E lead on pin 7 going from open circuit to closed circuit (with respect to the ground on pin 8). This off hook condition activates the pager system's control input, and the audio is sent on pins 4 and 5 of the voice port
For more information, refer to Using Analogue E&M ports to interface to Overhead Paging Systems.
Excellent document.......worked like a charm on CUCM9.1.....i used a CIPC and 7945......thanks Geevarghese Cheria
Very Crispy Document. I missed the Speed-Dial part of the configuration. Thanks very much. Geevarghese
Very good document.
But, one very important thing missing here is, "Default Activated Device" configuration on the Intercom line.
We must associate the phone's MAC on this field in order to get the Intercom line on the physical phone otherwise it would be blank with no functional Intercom line.

Yes i struggled at first, has anyone tired the new Singlewire Paging platform, its now layerd onto Call Manager, you can now deploy cisco and singlewire enabled intercoms. A good sell to the End User being: your SIP Intercom will also double as a paging IP Speaker, accpeting simultaneous sip and priority based multicasting.
Very Nice Document!!!
Is step 4 required? Can't we just use a regular Line DN line instead of having to modify the phone button template?
