1. A method for routing a communication in a telecommunications network, the method comprising:
receiving a communication from an ingress network to a telecommunications network, the communication comprising a upstream carrier identification code (CIC) value associated with an upstream network;
removing the upstream CIC value from the communication;
inserting a provisioned ingress network specific CIC value into a signaling information of the communication; and
transmitting the communication to an egress network of the telecommunications network with the provisioned ingress network specific CIC value in the signaling information of the communication.
