Abstract:
A telecommunications system for managing a call, the system comprising:a broadband network associated with a first device having a remote digital terminal (RDT) interface; a circuit switched network associated with a second device having an integrated digital terminal (IDT) interface; an interface device positioned between the first and second devices and operable to communicate with both the first and second devices to route the call, wherein the interface device acts as an IDT when communicating with the first device and acts as an RDT when communicating with the second device, and wherein the interface device accesses the second device only if the call is to be routed through the circuit switched network; and software executable on the interface device, wherein the software includes instructions for: intercepting a call request sent by the first device to the second device; determining a path by which to route the call; accessing the second device only if the path includes the circuit switched network; and routing the call via the path, wherein resources associated with the second device and circuit switched network are not used unless the path includes the circuit switched network.
