Abstract

A system for validating codec software includes sending to a validation server duplicates of the real-time endpoint encoder and decoder input/output datas. A comparator of the validation server compares the encoder output data to a pre-tested reference code and the decoder output data to a pre-tested reference code. The process continues for as long as the endpoints are in the live audio session or until the validation server terminates collection of data. In one embodiment, the comparator may send an error message to an alert device if a mismatch between the datas is encountered. The system may further include a speech quality evaluator for determining a real-time QoS of the networked speech. The evaluator collects the encoder output data of a first endpoint and the same data after traveling through the data network and presented as the decoder input data of a second endpoint to determine the QoS.
