About Trunk Burst


Bursting and sharing is functionality that allows for calls that go beyond the maximum number allowed on the trunk to borrow call capacity from another group trunk group within your enterprise.


The maximum group trunk group burst can’t exceed 20% of a group trunk group's maximum concurrent call limit. Bursting and sharing is initially set to false and is managed by AT&T. If your Enterprise wants to utilize or make changes to this functionality, contact your AT&T account representative.


The Trunk Burst setting on a group trunk group indicates whether your Enterprise is using this functionality or not. The setting is either true or false.
