Transport Protocol (RTP) stream to the pre-configured multicast address(es) on specific
channel(s) without involving SIP signaling. You can also configure the phone to receive an RTP
stream from pre-configured multicast listening address(es) on specific channel(s) without
involving SIP signaling. Up to 31 multicast listening addressed and channels can be configured
on your phone.
The IP phone supports 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. We recommend that you specify these
channels when broadcasting with Yealink IP phones running firmware version 81 or later.
The IP phone can only send and receives broadcasts to/from the listened channels. Other
channels’ broadcasts will be ignored automatically by the IP phone.
