Abstract
A session controller configured to receive a data packet from a packet-switched network having multiple communication links is disclosed. The disclosed session controller is further configured to define a call-routing policy based on layer-five information, layer-two information, layer-three information and layer-seven information from the data packet. The call-routing policy is configured to define a least-cost routing (LCR) call route for an ingress call over at least one of the plurality of communication links. The LCR call route is associated with an operational cost that is lower than an operational cost associated with at least one other call route over at least one communication link from the plurality of communication links. The session controller is also configured to associate the ingress call to an egress-call peer based on the call routing policy.
