6.4 Configuring Paging
Live announcements can be made (paged) from a phone to a group of phones to notify a
team (for example) that a meeting is about to commence. The paged announcement is
multicast via a designated group IP address, in real time, on all idle phones in the group,
without requiring listeners to pick up their receivers. The name of the group is displayed on
phone screens when the paging call comes in. A key for paging a group can be configured
using the configuration file or on the phone itself (see the User's Manual ).
 To configure paging:
• Use the table as reference.
