Abstract
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.
