ABSTRACT:
A method of operating a telecommunications network includes, in one embodiment, detecting a call at an originating switch of the telecommunications network and, when a destination for the call matches a predetermined destination, routing the call on designated data trunks. When traffic on the designated data trunks exceeds a capacity threshold, the method further includes routing the call to a terminating switch using interoffice trunks and completing the call to the destination from the terminating switch.
