Multicast Paging
Multicast Paging allows you to easily and quickly broadcast instant audio announcements to users who
are listening to a specific multicast group on a specific channel.
Yealink IP phones support the following 31 channels:

0: Broadcasts are sent to channel 0. Note that the Yealink IP phones running firmware version 80 or
earlier can be regarded as listening to channel 0. It is the default channel.

1 to 25: Broadcasts are sent to channel 1 to 25. We recommend that you specify these channels
when broadcasting with Polycom IP phones which have 25 channels you can listen to.

26 to 30: Broadcasts are sent to channel 26 to 30.
The IP phones can only send and receives broadcasts to/from the listened channels. Other channels’
broadcasts will be ignored automatically by the IP phone.
