Right, computers don't have 'opinions' (the 'O' in 'MOS'). However, it seems that many people use PESQ scores as a MOS-equivalent for test and planning purposes now. However, that requires running predefined samples through the system under test, not just calculations based on network effects of real calls. -- Kevin P.
