Configure a Paging Group (Multicast Paging)

You can configure multicast paging so that users can page all the phones at once or page a group of phones

group and can subscribe them to the same multicast address. This enables users to direct pages to specific
groups of phones. When you assign each paging group with a unique number, the user dials the paging group
number to start paging. All phones that are subscribed to the same multicast address (also configured on the
Configuration Utility page) receive the page. The user hears a paging tone of three short beeps when there is
an incoming paging call.
