The following describes 31 paging channels:
 0: You can broadcast audio to channel 0. Note that the Yealink IP phones running old
firmware version (old paging mechanism) can be regarded as listening to channel 0. It is
the default channel.
 1 to 25: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Polycom IP phones which have 25 channels you
can listen to.
 26 to 30: You can broadcast audio to a specific channel. We recommend that you specify
these channels when broadcasting with Yealink IP phones running new firmware version
(new paging mechanism).
The IP phones will automatically ignore all incoming multicast paging calls on the different
channel.
