[OpenSIPS-Users] RV: Very Strange Case

Do you have handling in error_route to capture parsing errors? You only provided a picture of a trace display, not the actual messages, so it is not possible to tell if the message is legit. If it is the exact same message being dropped every time, it is likely the message is misformatted.

Hi Razvan,

I know this is like a fantastic story, these points have already been proven;

1.- source and destination over 5060 port for all SIP traffic
2.- I don't use Pike
3.- No firewall rules
4.- Selinux is disabled

I am not tracing with Debug but I set xlog just below route{ and onreply_route{
The truth is that I am baffled...

Could it be that Opensips does not detect these messages as SIP type?  Or something like that?

Thank you very much.

Hi, Jorge!

If you are saying the 200 OK is not even logged (are you tracing with Debug), it means OpenSIPS doesn't see it. I would check:
1. the 200 OK is sent to the proper port
2. Pike is not blocking the reply
3. local firewall does not block the 200 OK
4. selinux is disabled

Best regards,

Hi all,

I've been using OpenSIPS for a long time and I have never seen anything like it.

The schema is very simple, OpenSIPS exchanges SIP traffic between SBC and Asterisk PBX, during a fax call in response a REINVITE packet a 200 Ok is ignore by OpenSIPS, not even writes in log, as if this packet did not exist. OpenSIPS always ignores the same SIP packet and its retries.

The sniffer on the Opensips interfaces shows that the packets are arriving correctly.

Does anyone think it might be happening?

Very Thanks.
