The Paging Server can transmit to Group Paging groups 1 through 25 only for one-way audio pages.
The transmit channel is configurable. The Polycom phones must subscribe to this channel in order to
receive one-way audio pages from the Paging Server.
When configuring Polycom phones for their Group Paging feature, be sure the following settings are
configured:
•
Payload Size = 20 ms (milliseconds)
•
Codec = G.711Mu
The Polycom Group Paging multicast transmitted by the Paging Server is G.711Mu encoded with a
payload size of 20 ms.
It is imperative to note the Paging Server assumes the Polycom phones will use an odd-numbered
port. Since it is not possible to configure the V3 Paging Server to transmit multicasts on odd-
numbered ports (which maintains conformance with RFC 1889), it is necessary to use the next lower
even port number when specifying the Polycom multicast IP address and port number on the
PGROUPS Configuration Page
. Using the Polycom default port 5001 will require you to configure
the Paging Server to transmit on the next lower even port 5000.
Thus, configuring the Paging Server for Polycom Paging is a two-step process:
1. Enable Polycom Paging on the Paging Server by checking the box to
Enable Polycom Paging
on Multicast
on the
Device Configuration Page
.
2. Specify the Polycom IP address and use the next lower even port number for the desired paging
group on the
PGROUPS Configuration Page
.
3. Save and reboot to store changes.
