Altigen ACM 6.7 Administrator's Manual page 271

When a member is added, its default state is Login. Paging group members can use #54
to perform group login or #56 to log off. If a member is logged off, then it will not receive
group paging.
To remove members assigned to a Paging Group:
1. On the Group Member tab of the Paging Group Configuration window, click the
extension(s) you want to remove in the Member list.
2. Click the Remove button to move them to the Not Member List.
Important:
• If an IP phone in a different network segment needs to be in a paging group, you
need to configure intermediate routers to pass through the IP multicast packets.
• IP paging to remote IP phones over WAN is not supported.
