Incoming/Outgoing Intercom with Auto-Answer

The Intercom feature allows you to press the configured Intercom button on the IP phone and then enter the number you want to call to initiate an intercom call. Intercom calls can be controlled either locally (phone-side) or by the SIP server (server-side).

Note: Auto-answer and intercom are applicable to all IP phone models. Outgoing intercom settings are applicable to the (55i, 57i, and 57i CT only.) A user can only set the incoming intercom settings on the IP phone. An administrator can set both the incoming and outgoing intercom settings.

Auto-Answer

The auto-answer feature on the IP phone allows you to enable or disable automatic answering for an Intercom call. If “Auto-Answer” is enabled, the phone automatically answers an incoming intercom call. If “Play Warning Tone” is also enabled, the phone plays a tone to alert the user before answering the intercom call. If “Auto-Answer” is disabled, the phone rejects the incoming intercom call and sends a busy signal to the caller.

Outgoing Intercom Calls (55i, 57i and 57i CT only)

On outgoing intercom calls, an available unused line is found when the Icom button is pressed. Since this line has no configuration, the phone applies an existing configuration ("Outgoing Intercom Settings", Line, default is Line 1) to this line in preparation for placing the intercom call. For example, an outgoing intercom call can use the configuration of line 1 but places the actual intercom call using line 9.

A phone-sideIntercom call indicates the phone is responsible for telling the recipient that an intercom call is being placed, while a server-sideintercom call means the SIP server is responsible for informing the recipient. Server-side calls require additional configuration of a prefix code. After pressing the Icom button and entering the number to call, the phone automatically adds the prefix to the called number and sends the outgoing call via the server.
