Abstract
An arrangement for routing calls from a source switch to a destination switch in a telecommunications network. If a direct trunk is available between the two switches, that trunk is used. Otherwise, the destination switch is queried to obtain availability data of trunks to that switch from intermediate switches of the network. This availability data is then compared with availability data of trunks from the source switch to the intermediate switches. A route is then selected using an intermediate switch having available trunks from the source switch and to the destination switch. If a route using lightly loaded trunk groups is available, that route is selected in preference to the use of a route using more heavily loaded trunk groups. Advantageously, routing is performed to dynamically optimize selection of a route based on the current state of the network.
