How to Configure Instant Group Call

Instant Group Calls allows the Customer Administrator to configure up to 20 distinct telephone numbers that will be automatically dialed by the system and added to an instant conference call every time a User calls the associated telephone number. Valid telephone numbers include internal extensions as well as all domestic, 10-digit telephone numbers.

Instant Group Call may be used in conjunction with Push To Talk (PTT) to simulate an internal paging solution. PTT is a feature available for all calling plans with the exception of Common Lines and Shared Lines.
