(]) 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 is applicable to all IP phone models, but the Intercom feature is applicable to the 480i and 480i CT only.

Outgoing Intercom Calls

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.

Incoming Intercom Calls

On incoming intercom calls, you can enable (turn ON) or disable (turn OFF) the microphone on the IP phone. You can also enable or disable auto-answer. If auto-answer is enabled on the IP phone, 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. By default, the microphone is disabled and auto-answer is enabled.
