Multicast Paging Group Configuration
Yealink phones support up to 31 groups for paging. You can assign multicast IP address with a channel for each
group, and specify a label to each group to identify the phones in the group, such as All, Sales, or HR.
Tip: You can set a DSS key as Multicast Paging key or Paging list key on the phone, which allows you to send announce-
ments to the phones with the pre-configured multicast address(es) on the specific channel(s). For more information, refer to
DSS Keys.
The following table lists the parameters you can use to configure a multicast paging group.
