A telephony bridging device operates within infrastructure that includes a packet data network (Internet) and the Public Switched Telephone Network (PSTN) telephony network and supports a coupled POTS telephony device. The telephony bridging device is operable to bridge calls between every two of the POTS telephony device, the PSTN network, and the packet data network (Internet). The telephony bridging device selectively bridges incoming calls to the POTS telephony device, to remote PSTN terminals, and to remote VoIP terminals based upon telephony bridging instructions. These telephony bridging instructions may be stored locally or remotely.
