Multicast Paging
Multicast Paging allows you to easily and quickly broadcast instant audio announcements to users who are listen-
ing to a specific multicast group on a specific channel.
Yealink phones support the following 31 channels:
l
0: Broadcasts are sent to channel 0. Note that the Yealink phones running firmware version 80 or earlier 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 phones which have 25 channels you can listen to.
l
26 to 30: Broadcasts are sent to channel 26 to 30.
The phones can only send and receives broadcasts to/from the listened channels. Other channels’ broadcasts will
be ignored automatically by the IP phone.
