International Classification:

H04M 700

US Classification:

379219, 37920201, 37922001

Abstract:

Network resources for a call between a calling party and a called party are allocated. The network resources for the call are reserved based on a reservation request. The network resources are reserved before any one network resource from the reserved network resources is committed. The reserved network resources for the call are committed when a called party indicates acceptance for the call.

US Classification:

379386, 379418, 379372, 379 8812, 379 2702

Abstract:

A ring back signal for a call between a calling party and a called party can be simulated. A ring back message associated with the call is received. The calling party is associated with a first network. The called party is associated with a second network. A prestored ring back signal is selected from a set of prestored ring back signals based on the ring back message and/or a called number for the call. The selected prestored ring back signal is associated with the second network and is different from a second prestored ring back signal associated with the first network. The prestored ring back signal is sent to the calling party.

US Classification:

37911422, 37911401, 37911421, 37911423

Abstract:

A call is forwarded by connecting the call between an originating location and a forwarding location without connecting the call through a terminating location. The originating location is associated with a calling party. The terminating location is associated with a dialed number. The terminating location and the forwarding location is associated with the called party. A bill for the call is apportioned between the calling party and the called party. The bill portion for the calling party is a function of the originating location and the terminating location. The bill portion for the called party is a function of the terminating location and the forwarding location.

International Classification:

H04L 900

US Classification:

713153, 370410, 713201

Abstract:

State information for a call between a calling party and a called party is established without maintaining the state information at a gate controller. A setup request for the call is received at an originating gate controller. The originating gate controller is connected to a trusted network. The calling party is associated with an originating interface unit coupled to an untrusted network. The setup request for the call is authorized. The authorized setup request is sent to the called party. State information for the call is formatted based on a setup acknowledgment message received from the calling party. The state information for the call is sent from the originating gate controller to the originating interface unit without maintaining the state information at the originating gate controller.

Assignee:

ATT Corp. - New York NY

International Classification:

H04L 1228

US Classification:

370401, 370230

Abstract:

Gates for a call between a calling party and a called party are coordinated. A timer associated with a first gate opened at an originating network edge device is initiated. A first gate open message is sent from the originating network edge device to the terminating network edge device. The first gate at the originating network edge device is released if the timer expires before at least one from the group of: (1) an acknowledgment based on the sent first gate open message is received from the terminating network edge device, and (2) a second gate open message is received at the originating network edge device from the terminating network edge device after the terminating network edge device has opened a second gate associated with the called party.

H04L012/28

US Classification:

370392, 370389

Abstract:

A call between a first network associated with a calling party and a second network associated with a called party is connected. The source address for packets associated with the call arc translated. The packets are sent from the calling party to the called party without the called party receiving the source address that indicates at least one from the group of a logical identity of the calling party and a geographical identity of the calling party.
