ABSTRACT:
Systems and methods are provided for passing through features from alternative network devices, such as cellular telephones, to plain old telephone system (POTS) devices. In a broad sense, the system includes an interface that bridges the alternative network devices to the POTS devices. The interface is configured to convey feature data contained within signaling data generated by the alternative network devices and pass the feature data through to the connected POTS devices. If the feature data is incompatible with the connected POTS devices, the interface is further configured to determine a compatible protocol for the connected POTS devices and translate the feature data into the compatible protocol.
