Multicast Paging
You can use multicast paging to quickly and easily broadcast time sensitive announcements to
people who are listening to a specific multicast group and a specific channel. You can configure
a paging key or paging list key on the phone, which allows you to send a Real Time Transport
Protocol (RTP) stream to the pre-configured multicast address(es) and channel(s) without
involving SIP signaling. You can configure the phone to receive an RTP stream from pre-
configured multicast listening address(es) and channel(s) without involving SIP signaling. You
can specify up to 31 multicast listening addresses and channels.
Yealink IP phone supports the following 31 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.
