I'm a student and doing symbian pjsip for my final project, I'm testing pjsip (symbian_ua) versus xlite voip client, I have this strange behaviour : xlite can make call to symbian_ua or symbian_ua_gui , but not the other way around could you explain it to me why ? I try also setup srtp, do secure signaling really needed ? if so do I have to create a certificate for this session ? if so where should I put this certificate ? on a web server or what ? -------------- next part -------------- An HTML attachment was scrubbed...
