First of all, forget about 1.0.1, it's too old. Secondly, get the latest 1.x branch from svn instead (or even the trunk, if you dare). Third, you should send your log of 1.x too so that we're not looking in the dark. Fourth, run pjsystest application. And last but not list, try adding this in your config_site.h: #define PJMEDIA_AUDIO_DEV_HAS_ALSA 1 ?Benny On Tue, Oct 4, 2011 at 4:26 PM, ?lvaro L?pez L?pez <lopezavila69 at hotmail.com> wrote: > Hi list, > > I have been using PJSUA 1.0.1 for a long time under a Linux Slackware distro > with kernel 2.6.16.16.
