Abstract

The present invention provides a service node capable of coordinating call processing for incoming calls intended for any one of multiple telephony devices of a given entity, such as a business or individual user. Switching devices, such as traditional telephony switches or internetworked gateways controlling call routing, are configured to interact with a service node to determine how to handle incoming calls to the telephony devices that they serve. As such, call processing rules, which are established by the entity, are applied to an incoming call to any of the entity'"'"'s telephony devices to effectively route calls to other ones of the telephone devices, route the call to a desired voicemail system, provide call screening or blocking, and any other desired call control activity. Based on the call processing rules for the given entity, the service node will instruct the corresponding telephony switches to handle the incoming call.

Claims

1. A method for allowing coordinated call processing among multiple telephony devices associated with an entity comprising:

a) establishing call processing rules for processing incoming calls to each of a plurality of telephony devices associated with an entity; and

b) for each incoming call to any one of the telephony devices;

i) receiving a message initiated by a switching device servicing the one of the telephony devices, the message indicative of an incoming call to be terminated at the telephony device;

ii) generating instructions defining how the switching device should process the incoming call based on the call processing rules; and

iii) effecting delivery of the instructions to the switching device, wherein the switching device will process the incoming call according to the instructions such that incoming calls to any of the plurality of telephony devices associated with the entity are processed in a coordinated fashion.

2. The method of claim 1 wherein the telephony devices are associated with different directory numbers or network addresses.

3. The method of claim 1 wherein at least two of the telephony devices are serviced by different switching devices.

4. The method of claim 1 wherein at least two of the telephony devices are supported by different communication networks.

5. The method of claim 4 wherein a first of the telephony devices is supported by a wireline network and a second of the telephony devices is supported by a wireless network.

6. The method of claim 1 wherein the instructions are adapted to cause the switching device to route the incoming call to another of the telephony devices.

7. The method of claim 1 wherein the instructions are adapted to cause the switching device to route the incoming call to a voicemail system.

8. The method of claim 1 wherein all incoming calls to any of the telephony devices are routed to a single voicemail system when routing to voicemail occurs.

9. The method of claim 1 wherein the instructions are adapted to cause the switching device to block the incoming call.

10. The method of claim 1 further comprising determining the identity associated with a caller and generating the instructions based on the identity of the caller.

11. The method of claim 10 wherein the instructions for a first caller are different than the instructions for a second caller

12. The method of claim 10 wherein the call processing rules facilitate call screening such that certain calls are routed to a select one of the telephony devices while others are routed to a voicemail system.

13. The method of claim 1 further comprising determining a time or date of the incoming call and generating the instructions based on the time or date.

14. The method of claim 1 further comprising determining line status and generating the instructions based on the line status.

15. The method of claim 1 further comprising determining a mobile terminal location and generating the instructions based on the mobile terminal location.

16. The method of claim 1 further comprising determining computer presence and generating the instructions based on the computer presence.

17. The method of claim 1 further comprising determining calendar information and generating the instructions based on the calendar information.

18. The method of claim 1 further comprising determining the one of the telephony devices to which the incoming call was originally directed and generating the instructions based on the one of the telephony devices.

19. The method of claim 1 wherein the instructions are adapted to cause the switching device to route the incoming call to the one of the telephony devices.

20. The method of claim 1 further comprising creating a plurality of profiles for the entity, each profile defining unique call processing rules to apply to the incoming calls to the telephony devices associated with the entity.

21. The method of claim 1 further comprising receiving information from the entity and establishing the call processing rules based on the information.

22. The method of claim 1 further comprising establishing call processing rules for a plurality of entities.

23. The method of claim 1 further comprising provisioning the switching devices serving the telephony devices to obtain call processing instructions from a service node when processing the incoming calls.

24. The method of claim 1 wherein the entity is an individual.

25. A system for allowing coordinated call processing among multiple telephony devices associated with an entity comprising:

a) an interface;

b) a processing system associated with the interface and adapted to;

i) establish call processing rules for processing incoming calls to each of a plurality of telephony devices associated with an entity; and

ii) for each incoming call to any one of the telephony devices;

(1) receive a message initiated by a switching device servicing the one of the telephony devices, the message indicative of an incoming call to be terminated at the telephony device;

(2) generate instructions defining how the switching device should process the incoming call based on the call processing rules; and

(3) effect delivery of the instructions to the switching device, wherein the switching device will process the incoming call according to the instructions such that incoming calls to any of the plurality of telephony devices associated with the entity are processed in a coordinated fashion.
