Hi Benny, We are trying to integrate (licensed) IPP G729 codec with PJSIP 0.7 and are facing some audio quality issues which I have traced to jitter buffer. I have our SIP log attached here (statements like - "Decoding done: No. of frames: 1, totalDecoded: 10, input size: 10, nbytes: 10, frame count: 1" are part of our G729 decode routine where frame count is incremented for each decoded frame). As you will see in the log, there is a sequence of "Frame lost!" statements. Actually, it throws a frame lost for every frame decoded. Our frame per packet value for G729 is 2. So that would suggest that for every RTP frame received we get the 1st G729 frame from the JB but lose the 2nd G729 frame (from the same RTP packet). Would you happen to have any clue as to why that is happenning? What other information can I provide you to help us more?
