A quick search in duckduckgo (or google if you like it more) "pjsip disable portaudio" returns many links where you can see how to disable PortAudio back end and to enable Alsa instead. Please, do your own research before asking in the mailing list, your chances of getting help will increase if you do. Read pjsip documentation about the file config_site.h which is the place to configure some settings besides the configure script.This link http://trac.pjsip.org/repos/wiki should become your holy book regarding pjsip. > > I tried current pjproject-svn (r4883) build with external portaudio > (svn1919).

Yes there is a problem to set the appropriate bit rate for your hardware, but since I don't know your hardware I can't tell for sure where the problem is. > 15:32:28.198 pjsua_aud.c ...Conf connect: 1 --> 0 > 15:32:28.198 conference.c ....Port 1 (sip:508047160 at 192.168.1.254) > transmitting to port 0 (HDA NVidia: ALC889A Analog (hw:0,0) (44KHz)) > 15:32:28.198 pjsua_aud.c ...Conf connect: 0 --> 1 > 15:32:28.198 conference.c ....Port 0 (HDA NVidia: ALC889A Analog (hw:0,0) > (44KHz)) transmitting to port 1 (sip:508047160 at 192.168.1.254) Per the log the conference bridge successfully connects the incoming and outgoing audio, but at 44KHz, which your hardware is unable (it seems) to be able to handle. But you should check first if it works with the Alsa back end. Have you ran the pjsystest application which is built along with the library? You should find it under pjsip-apps/bin IIRC. There is only one sound device on your hardware? Somewhere in your log output I see something about setting sound device. Try without manually setting the devices (in case you were doing it, if not just ignore this), pjsip will use the first sound device it finds. > All above looks all OK for me. > Unfortunately local->remote audio still isn't working. There is a section in the wiki devoted to troubleshoot audio related issues, you should check it. > Instead of, I have local MIC looped to local speakers. What do you mean? Are you sure you aren't connecting the mic audio to the audio playback only? Check this http://trac.pjsip.org/repos/wiki/Python_SIP/Media to get a better understanding of how pjsip handles audio. > Where issue might be? How can I know?

Yes, that is how sound in computers work. Be sure you are not running pulseaudio and that no other application is trying to use the audio device. In your first email you said you were running some kernel version, it is more useful if you say which distribution are you running instead, the kernel version is very much useless here. -- Saludos Ernesto Celis de la Fuente http://expressit.celisdelafuente.net
