Abstract

A method, apparatus and computer readable medium for call quality testing is presented. A query is transmitted over a communications network from a first location to a second location. The query results in an audio signal at the second location, which is received at the first location. The audio signal is analyzed by comparing the signal with a reference signal clip. A statistical parameter is generated, the statistical parameter indicative of a quality of the received signal.
