System and method for establishing a call being received by a trunk on a packet network
First Claim
1. A method for establishing a call over a packet network said method comprising:
- receiving, at a call control manager located on the packet network, a call request via an originating trunk on a packet network from an originating call device of a calling party;
determining, by the call control manager, a transmission path from the originating trunk to a terminating segment of a terminating call device;
determining status of the originating trunk;
determining status of the terminating segment, in response to a determination that the status of the originating trunk is normal;
responsive to a determination that the status of the originating trunk and terminating segment are within a first range, establishing the call between the originating and terminating call device over the transmission path at a first data rate;
responsive to a determination that the status of the originating trunk or terminating segment is within a second range, determining whether the originating trunk and terminating segment can operate at a lower data rate;
responsive to a determination that the originating trunk and terminating segment can operate at the lower data rate, establishing the call over the transmission path between the originating call device and terminating call device at the lower data rate, wherein establishing the call over the transmission path between the originating call device and terminating call device at the lower data rate includes sending an invite with a lower speed CODEC to the terminating segment and receiving a positive response message from the terminating segment; and
rejecting the call request if status of either the originating trunk or terminating segment is within a third range, and sending a reject message to the originating call device.

Abstract
A method for establishing a call over a packet network may include receiving a call request via an originating trunk on a packet network from an originating call device. Status of an originating trunk and terminating segment may be determined. If the status of the originating trunk and terminating segment are within a first range, the call between the originating and terminating call device over the determined transmission path at a first data rate may be established. Otherwise, if the status of the originating trunk or terminating segment is within a second range, a determination as to whether the originating trunk and terminating segment can operate at a lower data rate may be made, and, if so, the call may be established over the transmission path between the originating call device and terminating call device at the lower data rate.

9. A system for establishing a call over a packet network said system comprising:
-
a network interface configured to communicate over a network; memory configured to store executable instructions; a processing unit in communication with said network interface and said memory and configured to execute the executable instructions to; receive a call request via an originating trunk on a packet network from an originating call device; determine a transmission path from the originating trunk to a terminating segment of a terminating call device; determine status of the originating trunk; determine status of the terminating segment, in response to a determination that the status of the originating trunk is normal; responsive to a determination that the status of the originating trunk and terminating segment are within a first range, establish the call between the originating and terminating call device over the transmission path at a first data rate; responsive to a determination that the status of the originating trunk or terminating segment is within a second range, determine whether the originating trunk and terminating segment can operate at a lower data rate; responsive to a determination that the originating trunk and terminating segment can operate at the lower data rate, establish the call over the transmission path between the originating call device and terminating call device at the lower data rate, wherein establishing the call over the transmission path between the originating call device and terminating call device at the lower data rate includes sending an invite with a lower speed CODEC to the terminating segment and receiving a positive response message from the terminating segment; and reject the call request if status of either the originating trunk or terminating segment is within a third range, and sending a reject message to the originating call device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
