After pressing a Multicast Paging key on the phone, the Phone sends RTP to a
preconfigured multicast address(es) (IP:port). Any phone in the local network then
listens for RTP on the preconfigured multicast address(es) (IP:port). For both
sending and receiving of the multicast RTP there is no sip signaling involved. The
phone receiving RTP will display the preconfigured listening multicast label (Label) to
the user.
Note:
Multicast RTP is one way only- from sender to the multicast address(es) (receiver).
For outgoing RTP multicasts, all other existing calls on the phone will be put on
hold.
