Abstract

A Voice over Internet Protocol (VoIP) feature server provides a remote worker feature over a VoIP platform of an IP network. The remote worker feature facilitates an individual, who is assigned a telephone number at his/her home PBX, to receive telephone service from a remote PBX using the same telephone number.

Claims (36)

1. A system comprising:

a Voice over Internet Protocol (VoIP) feature server that provides a remote worker feature over a VoIP platform of an IP network to facilitate an individual, who is assigned a telephone number at his/her home PBX, to receive telephone service from a remote PBX using the same telephone number.

2. The system of claim 1 further comprising:

a first Integrated Access Device (IAD) at a location of the home PBX to communicate, to the VoIP feature server via the IP network, an incoming call for the telephone number that is received by the home PBX.

3. The system of claim 2 further comprising:

a second IAD at a location of the remote PBX, wherein the VoIP feature server is to receive the incoming call from the first IAD via the IP network, and to route the incoming call to the second IAD via the IP network.

4. The system of claim 3 wherein the second IAD is to provide the incoming call to the remote PBX, and wherein the remote PBX is to route the incoming call to a station associated with the telephone number.

5. The system of claim 1 further comprising:

an Integrated Access Device (IAD) at a location of the remote PBX;

wherein if an outgoing call placed by the telephone number at the remote PBX is a non-emergency destined call, the remote PBX routes the outgoing call to the IAD.

6. The system of claim 5 wherein the IAD is to route the outgoing call to the VoIP feature server via the IP network.

7. The system of claim 6 wherein the VoIP feature server is to process the outgoing call based on whether the outgoing call is a PBX-destined call or a Public Switched Telephone Network (PSTN)-destined call.

8. The system of claim 7 wherein the outgoing call is a PSTN-destined call, and wherein the VoIP feature server is to route the PSTN-destined call via the IP network to the home PBX.

9. The system of claim 8 wherein the home PBX is to complete the PSTN-destined call via a switch.

10. The system of claim 7 wherein the outgoing call is a PBX-destined call, and wherein the VoIP feature server is to route the PBX-destined call via the IP network to a destination PBX.

11. A method comprising:

providing a Voice over Internet Protocol (VoIP) remote worker feature over a VoIP platform of an IP network to facilitate an individual, who is assigned a telephone number at his/her home PBX, to receive telephone service from a remote PBX using the same telephone number.

12. The method of claim 11 wherein said providing the VoIP remote worker feature comprises:

receiving, by the home PBX, an incoming call for the telephone number; and

routing the incoming call from the home PBX to a VoIP feature server via the IP network.

13. The method of claim 12 wherein said providing the VoIP remote worker feature further comprises:

routing the incoming call from the VoIP feature server to the remote PBX via the IP network.

14. The method of claim 13 wherein said providing the VoIP remote worker feature further comprises:

routing the incoming call by the remote PBX to a station associated with the telephone number at the remote PBX.

15. The method of claim 11 wherein said providing the VoIP remote worker feature further comprises:

routing an outgoing call placed by the telephone number at the remote PBX to an Integrated Access Device (IAD) of the remote PBX.

16. The method of claim 15 wherein said providing the VoIP remote worker feature further comprises:

routing the outgoing call from the IAD to a VoIP feature server via the IP network.

17. The method of claim 16 wherein said providing the VoIP remote worker feature further comprises:

processing the outgoing call by the VoIP feature server based on whether the outgoing call is a PBX-destined call or a Public Switched Telephone Network (PSTN)-destined call.

18. The method of claim 17 wherein the outgoing call is a PSTN-destined call, and wherein said providing the VoIP remote worker feature further comprises:

routing the PSTN-destined call from the VoIP feature server to the home PBX via the IP network.

19. The method of claim 18 wherein said providing the VoIP remote worker feature further comprises:

completing the PSTN-destined call by the home PBX via a switch.

20. The method of claim 17 wherein the outgoing call is a PBX-destined call, and wherein said providing the VoIP remote worker feature further comprises:

routing the PBX-destined call from the VoIP feature server to a destination PBX via the IP network.
