Use the following procedure to configure LLDP-MED using the Aastra Web UI:
Incoming/Outgoing Intercom with Auto-Answer and Barge In
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).
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 con-
figuration, 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 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:
