Abstract
An end-user communication device comprises a telephony interface, network interface, and control circuitry. The telephony interface exchanges telephony signals with a telephone connection to a telephone. The network interface exchanges Internet Protocol (IP) packets with an IP interface for an IP connection to a first service provider. The control circuitry interworks between the telephony signals and the IP packets. For a set of the IP packets being transferred to the IP interface, the control circuitry places a first IP address in the first set of the IP packets for use by the first service provider to route the first set of IP packets over a peer-to-peer IP connection to a second service provider and places packet telephony network addresses in the first set of the IP packets for use by a packet telephony network in the second service provider to provide telephony service.
