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 6910 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 dependent on the setting for the Allow Barge In
parameter (see “Allow Barge In” on page clxxiv) 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.
