Abstract

Claims (43)

1. A simultaneous hunt group system comprising:

a first switch including a call status module for noticing an incoming call to the simultaneous hunt group and configured to offer the incoming call to an endpoint; and

a second switch including a call transfer module, the second switch communicatively coupled to the first switch and to the endpoint, the call transfer module configured to notice the endpoint accept the incoming call offer, and responsive to the noticing, allocate resources for transferring the incoming call.

2. The system of claim 1 wherein the first switch is grouped within a first site and the second switch is grouped within a second site.

3. The system of claim 1 wherein at least one of the first switch and the second switch is coupled to a public switched telephone network.

4. The system of claim 1 wherein the endpoint is one of an analog telephone, an IP telephone, and a computing device.

5. The system of claim 1 wherein the first switch and the second switch further include a resource management module for managing resource usage.

6. A simultaneous hunt group computing device comprising:

a call status module configured to notice an incoming call to the simultaneous hunt group and configured to offer the incoming call to an endpoint; and

a call transfer module configured to notice the endpoint accept the incoming call offer, and responsive to noticing the endpoint accept, allocate resources for transferring the incoming call to the endpoint.

7. The device of claim 6 further comprising:

a resource management module coupled to the call transfer module and configured maintain information about resource available on a resource-constrained communication link and to respond to resource reservation requests.

8. The device of claim 6 further comprising:

a reporting module coupled to the call transfer module and configured to report whether resource allocation is successful.

9. The device of claim 6 wherein the endpoints comprise at least one of Internet protocol telephones and analog telephones.

10. The device of claim 6 further comprising a workgroup server configured to include the call status module and the call transfer module.

11. The device of claim 6 further comprising a switch configured to include the call status module and the call transfer module.

12. The device of claim 11 wherein the endpoints are coupled to the switch.

13. A resource allocation method for a simultaneous hunt group, the method comprising:

noticing an incoming call;

determining a plurality of endpoints for the incoming call;

offering the incoming call to at least one of the plurality of endpoints;

noticing one of the plurality of endpoints accept the incoming call; and

responsive to noticing, allocating resources for transferring the incoming call to at least one of the plurality of endpoints.

14. The method of claim 13 further comprising:

determining whether resource allocation is successful; and

responsive to determining, initiating a transfer of the incoming call from to at least one of the plurality of endpoints.

15. The method of claim 13 wherein allocating resources further comprises reserving resources for at least one of a caller site and a callee site.

16. The method of claim 14 further comprising:

responsive to determining whether resource allocation is successful, reporting unavailability of resources to at least one of the incoming caller and at least one of the plurality of endpoints.

17. The method of claim 13 wherein allocating resources for transferring the incoming call further comprises:

determining an amount of resources needed to transfer the incoming call; and

updating status to apportion the amount of resources needed.

18. A resource allocation method for a simultaneous hunt group, the method comprising:

noticing an incoming call;

determining a plurality of endpoints for the incoming call;

responsive to determining the plurality of endpoints for the incoming call, allocating resources for a plurality of potential media paths to the plurality of endpoints;

offering the incoming call to at least one of the plurality of endpoints;

noticing one of the plurality of endpoints accept the incoming call; and

transferring the incoming call to the one of the plurality of endpoints that accepted the incoming call using at least one of the plurality of potential media paths.

19. The method of claim 18 further comprising:

releasing resources for the potential media paths that were not needed for transferring the incoming call.

20. The method of claim 18 wherein allocating resources further comprises reserving resources for at least one of a caller site and a callee site.
