Abstract

An originating device coupled to an originating network requests a media call to a terminating device coupled to a terminating network. In between the originating and terminating networks, a tandem network receives a signaling message for the media call transferred by the originating network. The tandem network retrieves and processes numbers for the originating device and the terminating device from the signaling message to determine a loss adjustment for the media call and to select the originating device or the terminating device to make the loss adjustment. The tandem network transfers a loss instruction indicating the loss adjustment to the originating network or the terminating network for delivery to the selected device. The selected device receives the loss instruction and responsively makes the loss adjustment.

Dependent claims

A method of operating a tandem network wherein an originating device coupled to an originating network requests a media call to a terminating device coupled to a terminating network, the method comprising:

in the tandem network, receiving a signaling message for the media call transferred by the originating network and retrieving a first number for the originating device and a second number for the terminating device from the signaling message;
processing the first number and the second number to determine a loss adjustment for the media call and to select one of the originating device and the terminating device to make the loss adjustment by processing at least the first number to determine if the originating device can make the loss adjustment and processing at least the second number to determine if the terminating device can make the loss adjustment;
and
transferring a loss instruction indicating the loss adjustment to one of the originating network and the terminating network for delivery to the selected device, wherein the selected device receives the loss instruction and responsively makes the loss adjustment for the media call.

1 more element

A tandem network wherein an originating device coupled to an originating network requests a media call to a terminating device coupled to a terminating network, the tandem network comprising:

a call processing system configured to receive a signaling message for the media call transferred by the originating network and process the signaling message to route the call from the originating network to the terminating network;
a routing system configured to transfer media communications for the media call between the originating network and the terminating network;
and
the call processing system further configured to process a first number for the originating device and a second number for the terminating device to determine a loss adjustment for the media call and select one of the originating device and the terminating device to make the loss adjustment by processing at least the first number to determine if the originating device can make the loss adjustment and processing at least the second number to determine if the terminating device can make the loss adjustment, and transfer a loss instruction indicating the loss adjustment to one of the originating network and the terminating network for delivery to the selected device, wherein the selected device receives the loss instruction and responsively makes the loss adjustment for the media call.
