Re: Miniua as echo tester

Hello, 

I tried to use Half Duplex (at least for testing), but I saw and mentioned a bug, and got this reply from Jérôme WAGNER:

There might be a bug ;
but the "PH_HDX_MODE_MIC" branch is
not tested/used 

So I stopped trying using half duplex.

About the 100% problem: did you see this on systems other than Windows? If no, then this could be a problem with PortAudio MME implementation which I'm using. By the way, how can I activate DirectSound instead of MME for WengoPhoneNG?

Thanks again for all of your replies.

I strongly suspect that the problem is in echo canceller code....
But i know that phmedia-audio.c  is strongly depended on various timing
related
fenomena...  So if latest portaudio changes something in timing
characteristics the problem
might go away...

The best way IMO is not to use AEC but to use HALF DUPLEX mode  (this
will not work for echo server, for echo server simply use -noaec on
miniua command line)
