Hi Benny This morning I have run about 1500 PESQ evaluations. As I told you, I have used pjsua 1.0-rc2 + changes coming from enhancement #638. In attach you can find the pjsua's configuration used: codec PCMU no vad no echo suppressor I am summing up the results: Result Minimum of OT.PesqScoreMin Average of OT.PesqScoreAvg Minimum of TO.PesqScoreMin Average of TO.PesqScoreAvg Total Executed Failed % TcRun # PASSED 3.56 4.38 3.26 4.38 150 150 0 150 A single test consists of 4 PESQ evaluations on each side of the call: OT.Pesq = PESQ performed on called side; TO.Pesq = Pesq performed on caller side. The speech sample is 7 seconds long and a call is about 1 minute long. You can see that the average of the PESQ score is good, but there is some test with low values. In general the PESQ score with lower value is related to the first evaluation of the call, but that it is not always true. Now I am doing the same tests after the activation of the VAD. The first results highlight that there is a considerable worsening of the PESQ measures stability. Let me now how to send you logs.
