System with call forward profile
First Claim
1. A method for forwarding at least voice over Internet Protocol (IP) calls, the method comprising:
- dialing a first telephone from a second telephone, to make a voice over IP call;
setting up the voice over IP call by at least transmitting a data packet via an IP network to a call manager which ensures that adequate network resources are available to accommodate the call;
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 stored call forwarding profiles to determine whether there is an active call forwarding profile for said first telephone;
connecting said voice over IP call to said first telephone if the active call forwarding profile is not found by said checking; and
connecting the voice over IP call to a third telephone based on a call forwarding information, if the active call forwarding profile is found by said checking;
wherein the call forwarding information is comprised in the active call forwarding profile and is created by use of at least a display, and the display is not integral to a customer premises equipment that conforms to the signaling protocol SIP;
wherein a new call destination number is transmitted in another data packet; and
wherein the call manager uses at least the new call destination number to connect the voice over IP call to the third telephone.

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.

8. A method for forwarding at least voice over Internet Protocol (IP) calls, the method comprising:
-
dialing a first telephone from a second telephone, to make a voice over IP call; setting up the voice over IP call by at least transmitting a data packet via an IP network to a call manager which ensures that adequate network resources are available to accommodate the call; 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 stored call forwarding profiles to determine whether there is an active call forwarding profile for said first telephone; connecting said voice over IP call to said first telephone if the active call forwarding profile is not found by said checking; connecting the voice over IP call to a third telephone based on a call forwarding information, if the active call forwarding profile is found by said checking; and using an alerting parameter in a call delivery message to instruct a customer premises equipment associated with 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.

9. A system for forwarding voice over Internet Protocol (IP) calls, the system comprising:
-
a plurality of telephones, each telephone having a unique identifier; a network device for routing at least the voice over IP calls between the plurality of telephones; means for setting up a voice over IP call from a first telephone to a second telephone, by at least transmitting a data packet via an IP network to a call manager which ensures that adequate network resources are available to accommodate the voice over IP call; 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 said memory, to determine whether there is an active call forwarding profile for said first telephone; means for connecting said voice over IP call to said first telephone if the active call forwarding profile is not found by said means for checking; means for connecting the voice over IP call to a third telephone by using at least a new call destination number, based on a call forwarding information, if the active call forwarding profile is found by said means for checking; means for transmitting the new call destination number in another data packet; a display not integral to a customer premises equipment, wherein the customer premises equipment conforms to the signaling protocol SIP; and means coupled to the display, for receipt of the call forwarding information to be stored in the active call forwarding profile. - View Dependent Claims (10, 11, 12, 13)
