Hi,
I've recently experienced an opensips outage. As I see from the logs
there was a brief DoS attack by sipvicious, then the attacker was
blocked by fail2ban. But after that appeared a huge number of "
incorrect port 0 in reply from rtp proxy" errors and the calls weren't
going through. I was not able to monitor this myself, eventually the
opensips was restarted. I'm going to upgrade from 1.6.2 to 1.6.4 and
enable rtpproxy debug so as to get more info next time that it happens.
I'm just wondering now if it this some known bug. Thanks,
