Abstract
A system and method for allocating trunks in order to minimize glare. Trunk groups between switches are subdivided and each subgroup uses different allocation algorithms. A first switch hunts a first subgroup using a first algorithm and the second subgroup using a second algorithm. The switch on the other end of the trunk uses the second algorithm to hunt on the first trunk subgroup, and the first algorithm to hunt on the second trunk subgroup. In order to minimize glare, a determination can be made that one of the two algorithms will have precedence, i.e., if both switches seize the same trunk, then the switch using the algorithm of higher precedence to set up its call.
