A communications adaptor comprising an adaptor first port; an adaptor second port; an adaptor third port; and a processor. The adaptor first port is configured to connect to an analog communications line. The adaptor second port is configured to connect to a data network. The adaptor third port is configured to connect to an analog telephony device. The processor is configured to determine that a first call setup request signal has been received at the adaptor first port. The processor is further configured, subsequent to such determination: (1) to transmit a second call setup request signal over the adaptor second port to an Internet Protocol (IP) telephony system over the data network; and (2) to transmit a third call setup request signal over the adaptor third port.
