Conditions
You can assign up to 50 IP phones in an Internal or All call paging group.
When using Unicast mode, there must be an available DSP recourse for each IP phone in
the page group at the time of the internal page. If the resources are less than the number of
IP phones, the page will be delivered to the IP phones with the lowest port numbers. IP
phones that cannot obtain a DSP resource will not receive the page.
IP terminals (DT7XX) via NAT cannot utilize Multicast paging. These terminals must use
Unicast paging.
The ability to assign Unicast or Multicast on an IP phone basis, is restricted to internal
paging only. Other Multicast features (External MOH, Background Music, Room Monitor)
cannot utilize Unicast.
For an IP terminal to utilize the Multicast feature the IP terminal must have a gateway
programmed to accomplish the multicast transmission. When an actual gateway device
does not exist on the network, a dummy gateway address on the same subnet must be
defined.
When utilizing Multicast mode and a page group consists of all IP phones, the page is sent
via a multicast message from the initiating phone. If a paging group has IP and TDM
phones, when an IP phone initiates the page, a message is sent to the GPZ-IPLE and the
GPZ-IPLE sends the Multicast message for the IP phones.
SIP DECT Wireless phones cannot receive an Internal Page.
When using the G.711 Codec for multicast paging, only 10ms, 20ms, 30ms, and 40ms
frame sizes can be used.
