System and method for transporting a call
View Patent ↗A communication processing system handles a plurality of calls. On a call-by-call basis for each of the calls, the system receives a control message indicating a route identifier for the call, receives a voice band communication for the call, and determines if the voice band communication should be compressed. If the voice band communication should be compressed, the system compresses the voice band communication, adds the route identifier from the control message to the compressed voice band communication, and transfers the compressed voice band communication with the route identifier. If the voice band communication should be not compressed, the system adds the route identifier from the control message to the voice band communication and transfers the voice band communication with the route identifier.
1. A method of operating a communication processing system to handle a plurality of calls, the method comprising:
on a call-by-call basis for each of the calls, receiving a control message indicating a route identifier for the call, receiving a voice band communication for the call, and determining if the voice band communication should be compressed;
if the voice band communication should be compressed, compressing the voice band communication, adding the route identifier from the control message to the compressed voice band communication, and transferring the compressed voice band communication with the route identifier; and
if the voice band communication should be not compressed, adding the route identifier from the control message to the voice band communication and transferring the voice band communication with the route identifier.
2. The method of claim 1 wherein determining if the voice band communication should be compressed comprises determining not to compress a modem communication.
3. The method of claim 1 wherein determining if the voice band communication should be compressed comprises determining not to compress a facsimile communication.
4. The method of claim 1 further comprising adding a compression indicator to the compressed voice band communication.
5. The method of claim 4 wherein transferring the compressed voice band communication with the route identifier comprises transferring the compressed voice band communication with the route identifier and the compression indicator.
6. The method of claim 5 wherein the compression indicator indicates a compression technique used to compress the voice band communication.
7. The method of claim 6 wherein the compression indicator is used to decompress the compressed voice band communication.
8. The method of claim 7 wherein the compression indicator comprises an asynchronous transfer mode convergence sublayer indicator.
9. The method of claim 1 wherein receiving the voice band communication comprises receiving the voice band communication from a circuit-based network.
10. The method of claim 1 wherein receiving the voice band communication comprises receiving the voice band communication from a DS0 connection.
11. The method of claim 1 wherein receiving the voice band communication comprises receiving the voice band communication from customer premise equipment.
12. The method of claim 1 wherein receiving the voice band communication comprises receiving a pulse code modulation signal.
13. The method of claim 1 wherein receiving the voice band communication comprises receiving an adaptive differential pulse code modulation signal.
14. The method of claim 1 wherein receiving the voice band communication comprises receiving an analog voice band communication.
15. The method of claim 14 wherein compressing the voice band communication comprises converting the analog voice band communication into a digital voice band communication and compressing the digital voice band communication.
16. The method of claim 1 wherein compressing the voice band communication comprises compressing a pulse code modulation signal.
17. The method of claim 1 wherein compressing the voice band communication comprises compressing an adaptive differential pulse code modulation signal.
18. The method of claim 1 wherein receiving the control message comprises receiving the control message over an internet protocol link.
19. The method of claim 1 wherein transferring the compressed voice band communication comprises transferring the compressed voice band communication over a broadband network.
20. The method of claim 1 wherein transferring the compressed voice band communication comprises transferring the compressed voice band communication over an asynchronous transfer mode network.
