Abstract

A switching system that receives communications over a trunk incoming from a communications network and routes them to its subtending communications terminals responds to a stimulus, such as actuation of an actuator, by either (a) returning all of the communications that it receives on the incoming trunk at least subsequently to the stimulus to the network over a trunk outgoing to the network with instructions directing the network to redirect the returned communications to a second switching system for routing to communications terminals served by the second system, or (b) routing all of the communications that it receives on the incoming trunk at least subsequently to the stimulus to the second switching system over a trunk outgoing to the second switching system for routing to the communications terminals served by the second switching system.

Claims

1. A method comprising:

repeatedly receiving communications from a communications network via an incoming trunk at a first switching system;

routing the received communications by the first switching system to communications terminals served by the first switching system;

in response to a stimulus received by the first switching system, the first switching system returning at least all of the received communications that were received by the first switching system subsequently to the stimulus via an outgoing trunk to the communications network with instructions directing the network to redirect the returned communications to a second switching system for routing of the redirected communications by the second switching system to communications terminals served by the second switching system.

2. The method of claim 1 further comprising:

in response to the instructions, rerouting the returned communications by the communications network to the second switching system.

3. The method of claim 2 further comprising:

routing the redirected communications by the second switching system to the communications terminals served by the second switching system.

4. The method of claim 1 wherein:

the first and the second PBX together form a failover arrangement.

5. The method of claim 4 wherein:

the failover arrangement comprises active/standby said switching systems.

6. The method of claim 4 wherein:

the failover arrangement comprises replicated said switching systems.

7. The method of claim 1 wherein:

the stimulus comprises actuation of an actuator.

8. The method of claim 1 wherein:

the stimulus comprises a feature access code.

9. The method of claim 1 wherein:

the instructions comprise associating an address with the communications by the first switching system.

10. The method of claim 9 wherein:

the associated address comprises an address of the second switching system.

11. The method of claim 1 wherein:

the instructions comprise prepending a first address by the first switching system to a second address of each of the communications.

12. The method of claim 11 wherein:

the first address comprises an address of the second switching system.

21. An apparatus for performing the method of one of claims 1-20.

22. At least one computer-readable storage medium containing instructions which, when executed by at least one computer, cause the at least one computer to perform the method of one of claims 1-20.

13. A method comprising:

repeatedly receiving communications from a communications network via an incoming trunk at a first switching system;

routing the received communications by the first switching system to communications terminals served by the first switching system;

in response to a stimulus received by the first switching system, the first switching system rerouting all of the received communications that were received by the first switching system via the incoming trunk at least subsequently to the stimulus to a second switching system via an outgoing trunk connecting the first switching system to the second switching system for routing of the rerouted communications by the second switching system to communications terminals served by the second switching system.

14. The method of claim 13 further comprising:

routing the rerouted communications by the second switching system to the communications terminals served by the second switching system.

15. The method of claim 13 wherein:

the first and the second PBX together form a failover arrangement.

16. The method of claim 15 wherein:

the failover arrangement comprises active/standby said switching systems.

17. The method of claim 15 wherein:

the failover arrangement comprises replicated said switching systems.

18. The method of claim 13 wherein:

the stimulus comprises actuation of an actuator.

19. The method of claim 13 wherein:

the stimulus comprises a feature access code.

20. The method of claim 13 wherein:

the outgoing trunk connects directly to the second switching system without intermediacy of a communications network or another switching system.
