Note that the Yealink IP phones running old firmware version (old paging mech-anism) 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 broadcastingwith Polycom IP phones which have 25 channels you can listen to.l 26 to 30: Broadcasts are sent to channel 26 to 30. We recommend that you specify these channels when broad-casting with Yealink IP phones running new firmware version (new paging mechanism).Note that all IP phones in the multicast paging group must be deployed in the same network, since a broadcast is used.The IP phone can only send/receive broadcasts to/from the listened channels.
