INCOMING/OUTGOING INTERCOM WITH AUTO-ANSWER AND
BARGE IN
The Intercom feature allows you to press the configured Intercom button to initiate an intercom
call (either by entering a number manually or automatically initiating the call if a number is
predefined). Intercom calls can be controlled either locally (phone-side) or by the SIP server
(server-side).
You can configure incoming and outgoing intercom calls on all phone models. A user can
configure incoming intercom calls 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. Only an Administrator can configure outgoing intercom calls.
A
phone-side
Intercom call indicates the phone is responsible for telling the recipient that an
intercom call is being placed, while a
server-side
intercom 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, if required, entering the number to call, the
phone automatically adds the prefix to the called number and sends the outgoing call via the
server.
For outgoing intercom calls, an administrator can configure the following parameters:
INCOMING INTERCOM CALLS
You can configure how the phone handles incoming intercom calls. You can receive incoming
intercom calls whether or not there are active calls on the phone. The way the phone handles
the call depends on the incoming intercom call configuration. The following paragraphs describe
the configuration parameters for incoming intercom calls.
Microphone Mute
You can mute or unmute the microphone on the IP phone for intercom calls made by the
originating caller. If you want to mute the intercom call, you enable this feature. If you want to
unmute (or hear the intercom call), you disable this feature.
