Abstract

A system for processing calls with a time division multiplexing (TDM) network and routing the calls via an internet protocol network is disclosed. The system may receive a call from a call originating device. The call may then be routed to a time division multiplexing switch at which call processing is performed to determine routing information for the call. The routing information may then be received at a first VoIP media gateway, and the call may then be routed by the first VoIP media gateway. Once the call is answered, the connection between the time division multiplexing switch and the VoIP media gateway may be terminated to enable the total number of terminations to be reduced, thereby creating a more efficient system.
