The IP Phone 9160 can be configured to respond to multicast pages and also to initiate
multicast pages with multifunction keys. IP addresses and ports associated with paging
zones must match between senders (multicast multifunction keys) and intended listeners. It
is not required for a phone to have listener zones configured for each multicast sender key;
a phone may page to zones it does not receive. Likewise, a phone can be configured to
listen to zones without having paging keys for those zones.
Proper operation of IP multicasting for paging requires that your local networking
equipment is configured to support the IGMP protocol, and multicasting. You should
consult with your IT staff to ensure that your network is properly configured to support
proper registration of multicast listeners using IGMP, and proper transmission of multicast
traffic across all subnets where phones will be connected. Ports used for other services
(such as SIP signaling) should not be selected for multicast paging.
