Abstract
A system and method for routing a mobile phone call over a voice and data network. A user places a call on a mobile phone to an end destination. The call is then routed to a telecommunications gateway, where the call is converted into a medium that is transferable over the voice and data network. The converted call is then sent over the voice and data network to another PSTN and finally to the end destination.
