Abstract:
1. A system for interfacing a telephony device with a plurality of communications networks, comprising: an interface configured to convert a first network signal compatible with a first communications network to a second network signal compatible with a second communications network, wherein the interface is further configured to convert the second network signal to the first network signal; at least one device connector configured to couple the telephony device to the interface; and an interface controller configured to interface with the at least one device connector and send audio-control signals to the audio relay, wherein the telephony device comprises at least one of a plain old telephone system (POTS) device, a cellular device, and a computer network device, wherein the interface includes an audio relay configured to receive a first audio-control signal and transmit an analog-audio signal between the telephony device and a network device interface configured to translate the analog-audio signal to a protocol compatible with the second communications network, in response to the received first audio-control signal, wherein the telephony device is compatible with the first communications network, wherein the analog-audio signal is indicative of the network device being in use, wherein the system is configured to allow the telephony device to communicate with each of a PSTN, a computer network using a VoIP signal, and a cellular network, wherein when the telephony device disconnects the disconnect is detected by the interface controller through the network device interface and generates a second audio-control signal which disables the audio relay and terminates the connection between the telephony device and the network device, and wherein during a communication with the computer network a disconnect causes the interface controller to further generate signaling data which instructs a computer telephony device to stop transmission and reception.
