Multicast Paging
Multicast Paging allows you to broadcast instant audio announcements to users who are listening to a
specific multicast group on a specific channel.
The phone supports the following 31 channels:
• 0: Broadcasts are sent to channel 0.
• 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 running new firmware
version (new paging mechanism).
Note: All IP phones in the multicast paging group must be deployed in the same subnet since a
broadcast is used. The 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
You can send paging to the phones with pre-configured multicast addresses on specific channels.
Before you begin
Your system administrator has set the paging group for your phone.
Procedure
1. Go to OK > Call Features > Paging.
On the CP930W/DDPhone, go to Menu > Features > Paging List.
On the CP935W, go to More > Features > Paging List.
If your system administrator has set only one paging list, the paging is sent directly.
2. Select the desired paging group.
3. Select Paging.
On the CP935W, select the desired paging group directly.
Note: Multicast RTP is the one-way paging 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.
Receiving Multicast Paging
Your system administrator has set a listening paging group for you, you can automatically receive a paging
call when the phone is idle.
When there is a voice call or a paging call in progress, or when DND is activated on your phone, the phone
handles the new paging call differently according to the multicast listening settings configured by your
system administrator.
Managing a Paging Call
During a paging call, you can manage it manually at any time.
