the paging list key on the phone, which allows you to send a Real Time Transport Protocol (RTP)
stream to the pre-configured multicast address(es) and channel(s) without involving SIP
signaling. You can configure the phone to receive an RTP stream from pre-configured multicast
listening address(es) and channel(s) without involving SIP signaling. You can specify up to 31
multicast listening addresses and channels.
