Abstract
Network architectures, methods, and operations for routing telephone calls are disclosed. A customer premise includes a conventional POTS dedicated communication line to a central office switch and a broadband connection to a data network. The central office switch and the data network are connected by a communication link. An incoming telephone call to the customer premise may be routed via the dedicated communication line. If the dedicated communication line is busy or otherwise unavailable, the central office switch may route the call to the data network service provider for completion to the customer premise via the broadband data network.
