IP phones can receive an RTP stream from the pre-configured multicast address(es)
without involving SIP signaling, and can handle the incoming multicast paging calls
differently depending on the configurations of Paging Barge and Paging Priority Active.
Paging Barge
This parameter defines the priority of the voice call in progress, and decides how the IP
phone handles the incoming multicast paging calls when there is already a voice call in
progress. If the parameter is configured as disabled, all incoming multicast paging calls
will be automatically ignored. If the parameter is the priority value, the incoming
multicast paging calls with higher priority are automatically answered and the ones
with lower priority are ignored.
Paging Priority Active
This parameter decides how the IP phone handles the incoming multicast paging calls
when there is already a multicast paging call in progress. If the parameter is configured
as disabled, the IP phone will automatically ignore all incoming multicast paging calls. If
the parameter is configured as enabled, an incoming multicast paging call with higher
priority is automatically answered, and the one with lower priority is ignored.
