Abstract
A system and method for communicating via a packet telephony distribution system is defined that includes a dual-use/analog phone or phone adapter. Any communication device incorporating the adapter can dynamically receive incoming calls and transmit outgoing calls over analog phone lines and over derived phone lines such as VoIP (Voice Over IP). When receiving or transmitting calls, the adapter and an associated gateway perform operations that enable simultaneous communication over the analog phone lines or derived phone lines from any combination of communication devices. In cooperation with the communication devices, the gateway further dynamically controls the incoming and outgoing calls over the analog phone lines and derived phone lines.
