iPECS protocol employs multi-cast to send of RTP packets to multiple devices at one time. This
improves efficiency and lowers traffic by sending a single multi-cast packet to multi-cast group
members. In particular, paging employs this multi-cast technique. However, since multi-cast is not
commonly supported outside of the LAN, uni-cast must be used to transport such signals
between routers. At the receiving Zone, a local VoIP channel receives the uni-cast signal from the
controlling MPB. The VoIP channel then converts the packet address to a multi-cast signal for
delivery to devices in the same Zone RTP Relay Group.
