Hi, here is the situation: a) I have a SIP client using PJMEDIA (VAD is off). We are using G711 codec b) I make a call from the SIP client to a cellular # (via an appropriate gateway) c) The SIP client hears _fantastic_ media quality (hardly any latency, no clipping, clear) d) The cellular client hears reasonable amount of clipping We verified RTP packet counts, latency and jitter logs - all is good, but the mobile user is still hearing this problem. So bottom line, we are assuming there is no issue with the network, it likely has to do with the quality of packets PJMEDIA is sending out. One guess is that maybe there is (lack of) echo supression etc going on in the SIP handset which is causing the sampled packets to be clipped. Can you advice on what parameters we need to explore in PJMEDIA to potentially resolve the cause of this?
