Abstract: An inmate communication system and method of using are described herein for obtaining a lowest session rate. The inmate communication system includes a session boarder controller (SBC) server that analyses data from multiple carriers, historical sessions, and additional factors such as quality of service to determine a lowest rate for the session. The SBC server then routes the session using the carrier that has the determined lowest rate for the session. Further, the SBC server is configured to include both local and location redundancies to avoid interruptions in session service.
