And so. WireShark useful program :) The test steps:
- We make a outgoing call - WireShark captures traffic - We record conversation in wav using sipxCallAudioRecordFileStart As a result, that has captured by WireShark (RTP traffic) - does not contain any problems, a sound clean and precise. And here that that is heard in headphones and that is written in wav - has problems. The first a little milliseconds the sound is clean, then silence of 5...6 seconds, then again the sound appears. No any errors in logs. To repeat this loss of a sound very difficultly, but it is possible. I can send captured traffic if it will help...
