Group Paging; Intercom Calls - Mitel 6863i User Manual

Group Paging

Push-to-Talk and Instant Group Call (Clearspan)
Your System Administrator can configure the phone to use paging through the Clearspan system. The Clearspan group
paging feature allows you (using SIP signalling) to unidirectionally page a predefined group of users by dialing an
assigned DN or extension. The group is called and connected in a multi-way conference with the caller. When the group
members' phones are set to Auto-Answer, their phones automatically answer the page.
Group RTP Paging (RTP Streams)
Your System Administrator can configure the phone to receive a Real Time Transport Protocol (RTP) stream from pre-con-
figured multicast address(es) without Clearspan and without involving SIP signaling. Your administrator can specify up to
five multicast addresses that the phone listens for on the network.
The 6863i in the local network listens for RTP on the preconfigured multicast address. The phone displays the Paging mes-
sage 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 dependent on the setting for the Allow Barge-In parameter. (See
"Allow Barge In" on page 38.) If this parameter is disabled, and there is no other call on the phone, then the paging is auto-
matically played via the default audio device.
If there is an existing call on the phone, the call initially displays in the ringing state. You have 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 incom-
ing 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.

Intercom Calls

By default, the IP phone allows incoming intercom calls to be automatically answered without having to set up an Icom
key on your phone. Your System Administrator can enable outgoing intercom calls on your phone. If enabled, you must
configure an Icom key on your phone to use for outgoing intercom calls. You must configure a programmable key with the
function, Icom.
Your System Administrator can change the behavior of how the phone handles incoming intercom calls by enabling/disa-
bling specific parameters.
