Operational Features
Incoming/Outgoing Intercom with Auto-Answer
(Intercom applicable to 480i/480i CT only)
The Intercom feature on the IP phones allows you to press the Icom button 
(
]) 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).
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.
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 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.
Note: 
Auto-answer is applicable to all IP phone models, but the Intercom 
feature is applicable to the 480i and 480i CT only.
