ABSTRACT:
A system and method for utilizing circuit switched and packet switched resources are disclosed. A voice communication system configured for routing calls from multiple users to circuit switched or packet switched resources generally comprises a hub in communication with at least one circuit switched channel, at least one packet switched channel, and a plurality of user devices. The system further includes a controller operable to select the circuit switched channel or the packet switched channel for connection with one of the user devices when a call is placed to or from the user device and a routing device operable to route the call from the user device to the selected channel.
