ABSTRACT:
Methods and apparatus are disclosed to self-configure a flexible residential gateway providing access to an external communications network, and providing communications with an in home network. An example flexible residential gateway may include at least one voice over Internet protocol (IP) (VoIP) processor, at least one VoIP coupler connecting VoIP signals between at least one VoIP processor and at least one telephone line. In such an arrangement, the VoIP coupler may be configurably capable to disconnect a battery feed voltage and ring voltages from a telephone line. The gateway may further include a switch controller capable of disconnecting the battery feed voltage and the ring voltages from at least one telephone line if POTS signals are detected on at least one telephone line.
