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.

Why it's free to use
- Filed March 31, 1998 and granted March 19, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 31, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 31, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
