Systems and methods for interfacing telephony devices with cellular and computer networks

A method for interfacing a plain old telephone system (POTS) device, cellular network device, and a computer network device with a plurality of communications networks, comprising:

• converting a first network signal compatible with a first communications network to a second network signal compatible with a second communications network at an interface;
• and
• converting the second network signal to the first network signal at the interface, wherein the interface is coupled to at least one of the POTS device, the cellular network device, and the 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 at least one of the POTS device, the cellular network device, and the computer network 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 at least one of the POTS device, the cellular network device, and the computer network device is compatible with the first communications network, wherein the analog-audio signal is indicative of the network device being in use, wherein an interface controller sends the audio-control signal to the audio relay, wherein the interface is configured to allow the at least one of the POTS device, the cellular network device, and the computer network device to communicate with each of a PSTN, a computer network using a VoIP signal, and a cellular network, wherein when the at least one of the POTS device, the cellular network device, and the computer network 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 at least one of the POTS device, the cellular network device, and the computer network 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.

A computer-readable medium having computer-executable instructions stored thereon which, when executed by a computer, will cause the computer to perform a method for interfacing a plain old telephone system (POTS) device, cellular network device, and a computer network device with a plurality of communications networks, the method comprising:

• converting a first network signal compatible with a first communications network to a second network signal compatible with a second communications network at an interface;
• and
• converting the second network signal to the first network signal at the interface, wherein the interface is coupled to at least one of the POTS device, the cellular network device, and the 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 at least one of the POTS device, the cellular network device, and the computer network 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 at least one of the POTS device, the cellular network device, and the computer network device is compatible with the first communications network, wherein the analog-audio signal is indicative of the network device being in use, wherein an interface controller sends the audio-control signal to the audio relay, wherein the interface is configured to allow the at least one of the POTS device, the cellular network device, and the computer network device to communicate with each of a PSTN, a computer network using a VoIP signal, and a cellular network, wherein when the at least one of the POTS device, the cellular network device, and the computer network 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 at least one of the POTS device, the cellular network device, and the computer network 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.
