Abstract

A method and system for providing call forwarding in an IP telephone network is disclosed. First, when a telephone number for a first telephone from a second telephone is dialed, the call is routing to a call manager. Call setup procedures with a BRG responsible for the first telephone are then initiated. The BRG then checks stored call forwarding profiles to determine whether there is an active call forwarding profile for the first telephone. The call is connected to the first telephone if an active call forwarding profile is not found. However, if an active call forwarding profile is found, the call forwarding information is sent to the call manager. The call is routed to at least a third telephone based on the call forwarding information.

Claims

1. A method for forwarding at least voice over Internet Protocol (IP) calls, the method comprising:

setting up a voice over IP call dialed from a second telephone to a first telephone by at least transmitting a data packet via an IP network to a call manager;

wherein the call manager comprises a resources database and a customer database, the customer database determining whether a telephone number is on or off the IP network;

the call manager checking a plurality of stored call forwarding profiles, to determine whether there is an active call forwarding profile for the first telephone;

if an active call forwarding profile is not found by said checking, connecting the voice over IP call to the first telephone; and

if the active call forwarding profile is found by said checking, connecting the voice over IP call to a third telephone based on a call forwarding information comprised in the active call forwarding profile, wherein a new call destination number in the call forwarding information is used to automatically connect the voice over IP call to the third telephone.

2. The method of claim 1 wherein:

the active call forwarding profile is created based on a subscriber'"'"'s entry on or selection of information displayed on a touch-sensitive screen.

3. The method of claim 1 further comprising:

recognizing a subscriber'"'"'s words, spoken into a microphone to create or modify at least a portion of the active call forwarding profile.

4. The method of claim 1 further comprising:

providing prompts on a display, to receive the call forwarding information to be stored in the active call forwarding profile.

5. The method of claim 1 wherein:

the new call destination number is transmitted through the IP network to a customer premises equipment associated with the second telephone.

6. The method of claim 5 further comprising:

interconnecting the customer premises equipment wirelessly with at least one device.

7. The method of claim 1 further comprising:

using an alerting parameter in a call delivery message to instruct a customer premises equipment associated with the third telephone to generate a distinctive ringing tone on the third telephone to notify a subscriber that the voice over IP call is a forwarded call and not a call originally directed to the third telephone.

8. The method of claim 1 wherein:

the active call forwarding profile specifies that calls are only to be forwarded during predetermined periods of time.

9. The method of claim 1 wherein:

multiple destination numbers including said new call destination number are transmitted via the IP network.

10. The method of claim 9 wherein:

the multiple destination numbers are transmitted simultaneously in another data packet.

11. A system for forwarding voice over Internet Protocol (IP) calls, the system comprising:

a plurality of telephones, each telephone having a unique identifier;

means for setting up a voice over IP call by at least transmitting a data packet via an IP network to a call manager;

wherein the call manager comprises a resources database and a customer database, the customer database determining whether a telephone number is on or off the IP network;

a memory storing call forwarding profiles;

means for checking stored call forwarding profiles in the memory, to determine whether there is an active call forwarding profile for a first telephone, when the first telephone is dialed from a second telephone to initiate the voice over IP call; and

means, responsive to the active call forwarding profile being not found by said means for checking, for connecting the voice over IP call to the first telephone; and

means, responsive to the active call forwarding profile being found by said means for checking, for connecting the voice over IP call to a third telephone based on a call forwarding information comprised in the active call forwarding profile, wherein a new call destination number in the call forwarding information is used to automatically connect the voice over IP call to the third telephone.

12. The system of claim 11 further comprising:

means for creating the call forwarding profile based on a subscriber'"'"'s entry on or selection of information displayed on a touch-sensitive screen.

13. The system of claim 11 further comprising:

means for recognizing a subscriber'"'"'s words, spoken into a microphone to create or modify at least a portion of the active call forwarding profile.

14. The system of claim 11 further comprising:

means for providing prompts on a display, to receive the call forwarding information to be stored in the active call forwarding profile.

15. The system of claim 11 further comprising:

means for transmitting the new call destination number through the IP network to a customer premises equipment associated with the second telephone.

16. The system of claim 11 further comprising:

means for wirelessly interconnecting the customer premises equipment with at least one device.

17. The system of claim 11 further comprising:

means for using an alerting parameter in a call delivery message to instruct a customer premises equipment associated with the third telephone to generate a distinctive ringing tone on the third telephone to notify a subscriber that the voice over IP call is a forwarded call and not a call originally directed to the third telephone.

18. The system of claim 11 wherein:

the active call forwarding profile specifies that calls are only to be forwarded during predetermined periods of time.

19. The system of claim 11 further comprising:

means for transmitting via the IP network, multiple destination numbers including said new call destination number.

20. The system of claim 19 wherein:

the multiple destination numbers are transmitted simultaneously in another data packet.
