Call Waiting for Incoming Call Distribution Group (Group Call Waiting)
When there are no available extensions in an incoming call distribution group, the group members can
receive the Call Waiting tone. To use this feature:
• Select the Group Call Waiting mode through system programming. This determines the distribution
method for waiting calls.
• Member extensions must assign the Call Waiting mode individually, or they will not be notified. (→

[ICD Group Button for Group Call Waiting]
The way that the Group Call Waiting feature works depends on the Group Call Waiting Distribution
method as follows:
a)
Ring: The Group Call Waiting feature activates for all busy member extensions (even when
the extensions do not have ICD Group buttons) simultaneously for only one incoming call—
additional calls will wait in a queue.
b)
UCD/Priority Hunting: The Group Call Waiting feature activates on an idle ICD Group button
located on busy member extensions in a certain order. (This order depends on the type: UCD
or Priority Hunting.) Calls will arrive at idle buttons until all ICD Group buttons are occupied—
additional calls will wait in a queue.
Note
In method b), if an extension has one or more ICD Group buttons for an incoming call
distribution group and all the ICD Group buttons on the extension are occupied, the Group
Call Waiting feature for the group will not work at the extension.
