Abstract

A Voice-over-Internet protocol (VOIP) communications network system that enables direct-dialed (single-stage) access to the Internet Protocol network from the circuit-switched network. Specifically, the VOIP network system includes a VOIP service implemented on a communications system which, after a customer number has been registered for the service, automatically recognizes calls from the registered customer'"'"'s telephone number and determines if the call can be routed as a VOIP call over the IP network. In embodiments of the present invention, the customer can register for the VOIP service by selecting both a provider and a calling plan or by only selecting a provider. The system can be implemented to handle intra-state, inter-state and international voice-band calls (for example, regular telephone calls, facsimile transmissions and modem initiated calls) using standard circuit-switched telephone lines, cable, twisted pair, digital subscriber line and wireless.

Claims

1. A method for routing a direct-dialed voice-band call, comprising:

receiving, by a routing component, the direct-dialed voice-band call from a calling party telephone number associated with a telephone in communication with a circuit-switched public switched telephone network, the direct-dialed voice-band call being associated with a destination number;

determining, by the routing component, the destination number is served by an internet protocol gateway by searching a database in communication with an internet protocol gateway serving the calling party telephone number;

routing, by the routing component, the direct-dialed voice-band call to the destination number that is served by the internet protocol gateway as a voice-over-Internet protocol telephone call, via a direct link from a local access provider network to an internet protocol gateway that bypasses the public switched telephone network located between the local access provider network and the internet protocol gateway, where the calling party telephone number is registered for a voice-over-internet protocol service and where the destination number of the direct-dialed telephone call is accessible by the voice-over-internet protocol service; and

initiating, by the routing component, a voice-over-internet protocol billing record to be generated for the direct-dialed voice-band call.

2. The method of claim 1, further comprising:

receiving a registration for the calling party telephone number for the voice-over-internet protocol service prior to the calling party placing the direct-dialed telephone call.

3. The method of claim 2, further comprising:

storing a voice-over-internet protocol service registration record for the calling party telephone number.

4. The method of claim 2, further comprising:

storing an allowable destination list, which identifies the destination numbers accessible using the voice-over-internet protocol service, prior to the calling party placing the direct-dialed telephone call.

5. The method of claim 1, wherein the routing the direct-dialed voice-band call to the destination number as a voice-over-Internet protocol telephone call when the calling party telephone number is registered for a voice-over-internet protocol service and the destination number of the direct-dialed telephone call is accessible by the voice-over-internet protocol service comprises:

determining a voice-over-internet protocol service registration record for the calling party telephone number exists; and

determining whether the destination number of the direct-dialed voice-band call is accessible by the voice-over-internet protocol service.

6. The method of claim 5, further comprising:

when the calling party telephone number is registered for the voice-over-internet protocol service and when the destination number of the direct-dialed voice-band call is accessible by the voice-over-internet protocol service, receiving an indication to route the direct-dialed voice-band call over the internet protocol network, otherwise, receiving an indication to route the direct-dialed voice-band call over the circuit-switched public switched telephone network.

7. The method of claim 6, wherein the initiating comprises initiating the billing record for the direct-dialed voice-band call when the indication is to route the direct-dialed voice-band call over the internet protocol network, wherein the billing record is associated with the calling party telephone number.

8. The method of claim 7, further comprising:

routing the direct-dialed voice-band call to the internet protocol network.

9. The method of claim 8, further comprising:

receiving a notice of the direct-dialed voice-band call clearing.

10. The method of claim 9, further comprising:

closing the billing record for the direct-dialed voice-band call.

11. A switch for performing operations comprising:

receiving a direct-dialed voice-band call from a calling party telephone number associated with a telephone in communication with a circuit-switched public switched telephone network, the direct-dialed voice-band call being associated with a destination number;

determining the destination number is served by an internet protocol gateway by searching a database in communication with an internet protocol gateway serving the calling party telephone number;

routing the direct-dialed voice-band call to the destination number that is served by the internet protocol gateway as a voice-over-Internet protocol telephone call, via a direct link from a local access provider network to an internet protocol gateway that bypasses the public switched telephone network located between the local access provider network and the internet protocol gateway, where the calling party telephone number is registered for a voice-over-internet protocol service and where the destination number of the direct-dialed telephone call is accessible by the voice-over-internet protocol service; and

initiating a voice-over-internet protocol billing record to be generated for the direct-dialed voice-band call.

12. The switch of claim 11, wherein the operations further comprise:

receiving a registration for the calling party telephone number for the voice-over-internet protocol service prior to the calling party placing the direct-dialed telephone call.

13. The switch of claim 12, wherein the operations further comprise:

storing a voice-over-internet protocol service registration record for the calling party telephone number.

14. The switch of claim 12, wherein the operations further comprise:

storing an allowable destination list, which identifies the destination numbers accessible using the voice-over-internet protocol service, prior to the calling party placing the direct-dialed telephone call.

15. The switch of claim 11, wherein the operations further comprise:

when the calling party telephone number is registered for the voice-over-internet protocol service and when the destination number of the direct-dialed voice-band call is accessible by the voice-over-internet protocol service, receiving an indication to route the direct-dialed voice-band call over the internet protocol network, otherwise, receiving an indication to route the direct-dialed voice-band call over the circuit-switched public switched telephone network.

16. The switch of claim 15, wherein the initiating comprises initiating the billing record for the direct-dialed voice-band call when the indication is to route the direct-dialed voice-band call over the internet protocol network, wherein the billing record is associated with the calling party telephone number.

17. The switch of claim 11, wherein the operations further comprise:

routing the direct-dialed voice-band call to the internet protocol network.

18. The switch of claim 17, wherein the operations further comprise:

receiving a notice of the direct-dialed voice-band call clearing.

19. The switch of claim 18, wherein the operations further comprise:

closing the billing record for the direct-dialed voice-band call.
