An Internet Protocol telephone system and method uses a telephone ( ) to place and receive voice over Internet Protocol (VoIP)-based telephone calls and public switched telephone network (PSTN)-based telephone calls. An off-hook condition with the telephone ( ) is detected and a sequence of signals generated by the telephone ( ) is received. At least a first signal generated by the telephone ( ) is buffered while the system attempts to detect a predetermined signal that signifies a VoIP-based call. Upon detection of the predetermined signal, the system intercepts subsequent signals in the sequence, absent the at least first signal that was buffered, and places the VoIP-based call via an internet ( ). Otherwise, the system places the PSTN-based call via a PSTN ( ).

Voice over internet protocol telephone system and method

A method for secure registration of a access device (400) having a receiver (418) and a transmitter (420) transmitting at an operational RF power level with a base station (200) having a receiver (218) and a transmitter (216) in which the base station reduces its operational RF power level to a registration RF power level and transmits a registration invitation message (610) to an access device (400), wherein the base station (200) after receiving a registration response message (614) from the access device (400) restores its power level to the operational RF power level.

Method and apparatus for secure registration within an in-home wireless

An Internet Protocol telephone system and method uses a telephone (26) to place and receive voice over Internet Protocol (VoIP)-based telephone calls and public switched telephone network (PSTN)-based telephone calls. An off-hook condition with the telephone (26) is detected and a sequence of signals generated by the telephone (26) is received. At least a first signal generated by the telephone (26) is buffered while the system attempts to detect a predetermined signal that signifies a VoIP-based call. Upon detection of the predetermined signal, the system intercepts subsequent signals in the sequence, absent the at least first signal that was buffered, and places the VoIP-based call via an internet (12). Otherwise, the system places the PSTN-based call via a PSTN (16).
