Multicast Paging
Multicast Paging allows you to broadcast instant audio announcements to users who are listening to a specific
multicast group on a specific channel.
The phone supports the following 31 channels:
l
0
: Broadcasts are sent to channel 0. Note that the IP phones running old firmware version (old paging
mechanism) can be regarded as listening to channel 0. It is the default channel.
l
1 to 25
: Broadcasts are sent to channel 1 to 25. We recommend that you specify these channels when
broad- casting with Polycom IP phones which have 25 channels you can listen to.
l
26 to 30
: Broadcasts are sent to channel 26 to 30. We recommend that you specify these channels when
broad- casting with IP phones running new firmware version (new paging mechanism).
Note
: All IP phones in the multicast paging group must be deployed in the same subnet since a broadcast is used. The
phone can only send/receive broadcasts to/from the listened channels. Other channels
’
broadcasts will be ignored
automatically by the IP phone.

Sending Multicast Paging
Your phone supports up to 31 groups for paging. You can assign a label to each group to identify the phones
in the group, such as All, Sales, or HR.
You can set a line key as Multicast Paging key or Paging List key on the phone, which allows you to send
announcements to the phones with pre-configured multicast address(es) on specific channel(s).
Note
: Multicast RTP is one way only from the sender to the multicast address(es) (receiver). For outgoing RTP
multicasts, all other existing calls on the phone will be placed on hold.
