Hi All, I am a new learner of pjproject, but so far I can not lanuch the program al_pjsua. Firstly, I downloaded the newest tarball file pjproject-2.2.1.tar.bz from the official website. Secondly, followed the instruction of "http://trac.pjsip.org/repos/wiki/3rd_Party_Media_20" to compile the source code succesfully and generated the target program alt_pjsua . Thirdly, Did a test call to Asterisk or other server, all sip / rtp session worked well. But while the call terminated, alt_pjsua crashed at code "pj_assert(user_data == udp->user_data)" of function transport_detach in file transport_udp.c I did not modify any source code of pjproject-2.2.1.tar.bz. and the configure arguments is "./configure --disable-video --disable-speex-aec --disable-l16-codec --disable-gsm-codec --disable-g722-codec --disable-g7221-codec --disable-speex-codec --disable-ilbc-codec --disable-sdl --disable-ffmpeg --disable-v4l2 --disable-ssl --disable-opencore-amr --disable-silk" Can Someone help to fix the problem, Thanks All. ------------------ Original ------------------ From: "pjsip-request";<pjsip-request@xxxxxxxxxxxxxxx>; Date: Sun, Mar 16, 2014 09:24 PM To: "?????"<646650064 at qq.com>; Subject: Welcome to the "pjsip" mailing list Welcome to the pjsip mailing list!
