Group Rtp Paging - Mitel 6865i User Manual

Mitel 6865i SIP Phone Release 4.1.0 User Guide

GROUP RTP PAGING

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 Mitel Web UI only.
The 6865i 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 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
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.
