Hello, I try to build a small hidden SIP client for windows, that connects to asterisk in lan and autoanswer calls in background. Building with VS 2005 and desired functionality works fine but i discover differences in speech quality when i compare to softphone like 3CXPhone or Zoiper (i use asterisk Echo() for testing). In simple_pjua the voice sounds more flanelly, a little bit like you sit in a tin can. When the voice gets to loud, its like a strange distortion. In all cases i used PCMA as codec. In simple_pjsua.c I changed clock-rate of media-cfg to 64000. I also tried recfile to compare the quality - there are no problems. The resulting wav file sounds fine. Also the incoming Audio sounds good. Is there anything I miss? Regards Izaak -------------- next part -------------- An HTML attachment was scrubbed...
