By the way, I noticed that with pjsip coreaudio supoprt there is a significant delay when making a call (after hitting enter for SIP URI in pjsua, for example), comparing to pjsip build with portaudio. Also, the app linked against pjsua-lib built with coreaudio support doesn't work on Mac OS X 10.5, because it uses API introduced only in 10.6. It crashes trying to call AudioComponentFindNext().
