What fax application are you using? Recognize that if the fax applications are using ECM they will very likely fix at least some (if not all) of the data corrupted by line/audio quality problems before finishing. So when ECM is used the sent image and the received image can be identical even when the line had very poor audio quality. Thanks, Lee.
