Patent ID: 7623550

Claim:
A method in a computer system having a memory and a processor for adjusting CODEC parameters during a call, the method comprising: receiving an incoming call for emergency services, the incoming call comprising encoded data, wherein the encoded data is produced by a CODEC having at least one adjustable parameter and wherein the CODEC is configured to filter background noise from the incoming call; decoding the encoded data; playing the decoded data so that it can be heard by an operator; receiving an indication of a determination that the CODEC is filtering too much background noise from the incoming call, the determination having been made by the operator after hearing the played decoded data; displaying to the operator a user interface for adjusting the background noise filter of the CODEC; receiving from the operator an indication to adjust the background noise filter of the CODEC; sending by the processor a request to change a first parameter and a second parameter of the CODEC, the second parameter for adjusting the background noise filter so that the CODEC filters less of the background noise from the incoming call; and auditing the requested change by storing an indication of the requested to change the first parameter and the second parameter of the CODEC.
