  • a landline communication device comprising circuitry adapted to place and receive calls over a landline communication network; and

    interface circuitry connected to a single ring-tip line pair of a landline communication network and to a wireless communication device for a wireless communication network, wherein the interface circuitry selectively connects the landline communication device to the ring-tip line pair so that calls are placed and received by the landline communication device over the landline communication network and to the wireless communication device so that calls are placed and received by the landline communication device over the wireless communication network via the wireless communication device,wherein the interface circuitry detects if the ring-tip line pair is in use and, if so, automatically places calls from the landline communication device using the wireless communication device.
