172 Model 9143i IP Phone User Guide
Additional Features
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 multicast address(es) without involving SIP signaling. This is called Group
Paging on the IP phones. You can specify up to 5 multicast 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 preconfigured 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 “Allow Barge In” on page 170.) 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.
If an RTP multicast session already exists on the phone, and the phone receives another
incoming RTP multicast session, the priority is given to the first multicast session and the second
multicast session is ignored. The behavior for the incoming calls in this case is also based on the
setting for the “Allow Barge-in” parameter. The incoming call is handled as if there were an
existing call already on the phone.
