Low PESQ scores on EVRC-B loop back test compared with a test with a trans-media server between G711 and EVRC-B codec


The signal distortion on encoding and decoding of EVRC-B is much higher than G711.  For a back to back EVRC-B test, the signal is undergoing these distortion during the process.  In the case of G711 -- transmeida server -- EVRC-B test, there is only one encoding or decoding on the EVRC-B side.  Hence the overall signal distortion is smaller, resulting in a better PESQ.
