Configuring Incoming Intercom Settings
Use the following procedure to configure incoming Intercom settings on the IP phone.
Using Redial Key for “Last Number Redial”
The IP phone has an enhanced redial user interface that allows a user to quickly redial the last number that was dialed out
from the phone. You can:
•
Press the
Redial
key twice to redial the last number dialed.
•
Press the
Redial
key once, scroll the list of numbers, then press the
Redial
key again to dial the number that displays on
the screen.
The “last number redial” feature for the
Redial
key is static and is not configurable.
Group RTP Paging
(receives RTP streams)
You can configure the phone to allow it to receive a Real Time Transport Protocol (RTP) stream from pre-configured multi-
cast address(es) without involving SIP signalling. This is called Group Paging on the IP phones. You can specify up to 5 mul-
ticast addresses that the phone listens for on the network. This feature is configurable using the Aastra Web UI only.
The 9143i in the local network listens for RTP on the pre-configured multicast address. The Phone displays the “Paging”
message to the phone’s LCD. It uses the G711 uLaw CODEC for multicast RTP.
The recipient can drop the incoming page if required. The recipient can also set Do Not Disturb (DND) to ignore any
incoming pages.
For incoming RTP multicasts, the ringing display is dependant on the setting for the “
Allow Barge-In
” parameter. (See
.) If this parameter is disabled, and there is no other call on the phone, then the paging is
automatically played via the default audio device.
If there is an existing call on the phone, the call initially displays in the ringing state. The user has the option to
accept/ignore the call. If the “
Allow Barge-In
” parameter is enabled, the RTP multicast call barges in, and any existing calls
are put on hold.
