Hi, I built PJSIP and run on Freescale ARM i.MX53. The video call works well. The issue is with the audio. The call gets initiated from the i.MX base board to a mobile running the csipsimple android app. The audio is heard properly on the mobile but not on the i.MX board. The audio is heard clearly on for 1-2 secs and it starts to fade out or distorted. Sometimes audio is both distorted and faded. I tried all the steps in the audio troubleshooting as mentioned in the PJSIP website. I checked my sound output by playing an audio file. It plays well. Following steps I tried. 1. Tried using PCMU and PCMA as the board supports only PCM. SPEEX is disabled on the board. 2. Disabled the echo canceller. Did not have any effect on the result. 3. In-call volume to increased 5.0x, 10.0x and went up to 100.0x. Every time I increased this the audio gets worser. 4. Tried forcing 8KHz sample. Still no improvement. Can you suggest what could fix my issue? I could not get the packet statistics. Somehow the TX and RX packet count always shows zero when I use the 'dq' while in call.
