1. A system for providing a service that facilitates real-time voice communication between devices connected to an Internet Protocol (IP) network and devices connected to a public switched telephone network (PSTN) having voice circuits, the system comprising:

  • a gate interface circuitry communicatively coupled with the IP network and the voice circuits of the PSTN, wherein the gate interface circuitry is configured to;

    receive, via the IP network, a first call from a first device intended for a first subscriber of the service, wherein the first call comprises packetized voice data, anddepacketize the packetized voice data;

    a voice response unit communicatively coupled with the gate interface circuitry and configured to;

    receive the depacketized voice data from the gate interface circuitry, andconvert the depacketized voice data to digital tones; and

    a computer control interfacing with a switch and communicatively coupled with the gate interface circuitry and the voice response unit, wherein the computer control is configured to;

    store, for at least one subscriber of a plurality of subscribers of the service, at least one destination address on the PSTN and at least one destination address on the IP network, andcontrol the switch to route the first call on the PSTN, using the converted digital tones, to a second device of the first subscriber based on a first stored destination address.
