Abstract
A method and apparatus for enabling a call originated in the VoIP network to be routed from the egress of the VoIP network to the terminating PSTN network using an egress route, such as an appropriate egress access trunk, that is in the same Local Calling Area (LCA) of the called party number are disclosed. This allows the call to be completed to the called party without paying access charge. For example, the method assigns a Billing Telephone Number (BTN) or a Charge Number (CgN) to an egress route between a communication network and a Public Switched Telephone Network (PSTN) network. The method then routes a call originating from the communication network and terminating to the PSTN network using the egress route without incurring an access charge.
