I used the -trace_err to see what the errors where, and the problem is that while Sipp is expecting a particular response, it receives another, for example, while expecting and acknowledge it receives an OK. I used wireshark to see what was happening, and i saw that the Opensips server introduces a little delay in sending each response, but what I don't understand is why with such a small call rate I'm having this problem.<br>> ><br>> ><br>> ><br>> ><br>> > Luis,<br>> > You didn't answer my logging questions. I've seen bad logging configurations totally disable an opensips server. Specifically a registration server that could handle ONE phone but not TWO. No kidding. Problem was 100% syslog setup.
