Sending Multicast Paging; Setting A Multicast Paging Key - Yealink SIP-T48S User Manual

1 to 25: Broadcasts are sent to channel 1 to 25. We recommend that you specify these channels when broadcasting
l
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 broad-
l
casting with Yealink IP phones running firmware version 81 or later.
Note that all IP phones that you want to include in the multicast paging group need to be in the same network, since a
broadcast is used. The IP phone can only send/receive broadcasts to/from the listened channels. Other channels'
broadcasts will be ignored automatically by the IP phone.

Sending Multicast Paging
Yealink IP phone supports up to 31 groups for paging. You can assign a label to each group to identify the phones in
the group, such as All, Sales, or HR.
You can set a line key as Multicast Paging key or Paging list key on the phone, which allows you to send announce-
ments to the phones with pre-configured multicast address(es) on specific channel(s).
Note
Multicast RTP is one way only from the sender to the multicast address(es) (receiver). For outgoing RTP multicasts, all other
existing calls on the phone will be placed on hold.
