The Intercom feature allows you to speak to someone on an intercom line. Cisco CallManager does not have a dedicated Intercom feature. However, with Cisco CallManager, you can configure a phone/directory number to auto answer with speakerphone, which acts like an intercom. The configuration of this option causes the speakerphone to go off hook automatically when an incoming call is received.

Complete these steps in order to configure the Auto Answer feature:
On the Cisco CallManager Administration page, choose Device > Phones and select Extension.
Under the Directory Number Settings, go to Auto Answer and choose Auto Answer with speakerphone.
This acts like an Intercom feature for the directory number.
Note: The Auto Answer feature is not supported on shared lines. If required, you can use a third party solution called Berbee's InformaCast which provides the capability to simultaneously send an audio stream and a text message to Cisco IP phones (7940 or 7960).
For all incoming calls to the configured directory number, verify that the speaker phone automatically goes off hook.
