Hi, I just checked out the latest revision(1824), and now I'm not able to make a call between two instances running on the sam host. Instance 1: ./pjsua-i686-pc-linux-gnu --local-port=6028 --no-vad --ec-tail=0 --auto-answer=200 Instance 2: ./pjsua-i686-pc-linux-gnu --auto-loop --no-vad --ec-tail=0 --auto-answer=200 --null-audio When I make a call from instance 1 to sip:127.0.0.1, instance 2 freezes after receiving the initial INVITE. The last time I tried this was with revision 1786, which worked just fine. Thanks, Dan
