A bridging computing device includes processing circuitry communicatively coupled to a user interface, a Public Switched Telephone Network (PSTN) interface, a packet data network interface. The processing circuitry receives a first call setup request from the PSTN via the first interface, selectively prepares a second call setup request based upon the first call setup request, and sends the second call setup request to the Internet via the second interface. The processing circuitry may obtain and use bridging instructions to prepare the second call setup request. The processing circuitry may receive the first call setup request via the PSTN interface or the packet data network interface. The processing circuitry may send the second call setup request via the PSTN interface or the packet data network interface. The bridging computing device may optionally bridge a corresponding call and/or enable another bridging device to bridge the call.
