This is with regards to Echo Cancellation in C++/PJSIP classes: The method of AudDevManager is to be used to set Echo Cancellation: * @param tail_msec The tail length, in miliseconds. Set to zero to * disable AEC. * @param options Options to be passed to pjmedia_echo_create(). * Normally the value should be zero. void setEcOptions(unsigned tail_msec, unsigned options) throw(Error); Is there an example code which can be shared showing how to effectively use this API to manage echo cancellation. Thanks for your help!! Regards, Sanjay Read on how www.safetylink.org <http://www.safetylink.org/index.html> saves lives.

I took a look at the crashdump and the source code of stun_session.c where the segfault occurs. It seems the relevant code segments are similar in versions , 2.2-2.4 therefore I ask straight away rather than upgrading to latest pjnath and waiting for next crash (crashes occur less than every 2 weeks) http://pastebin.com/DiVyUgTkhttp://pastebin.com/DiVyUgTk I want to ask what is supposed to prevent t from being 0x0 in that function (before calling t->...) I'm thinking of adding a 't &&' in those while and if conditions... -------------- next part -------------- An HTML attachment was scrubbed...
