Hi Rasvan Crainea.

Thank you very much for the reply!

You gave me new points to  be checked and understood.

I will work for a while in such points and then I will give you a feedback.

So, wait for my next post, please.

Best regards.

Hi, Rodrigo!

Sorry, I've just seen the message, I've missed it earlier.

As far as I understand, OpenSIPS is listening on two interfaces: 127.0.01:5060 and 192.168.0.101:5060. Is the UPDATE coming on the same TCP connection as the initial one? Or the client opens a new connection for it, over the PUBLIC interface? Could you send over (privately) a PCAP trace?
Also, you'd probably need to make sure that you call fix_nated_contact() and force_rport() on the UPDATE request. Also, are you setting the tcp_accept_aliases[1] or force_tcp_alias()[2] in your script?

OpenSIPS is a mature Open Source implementation of a SIP server. OpenSIPS is more than a SIP proxy/router as it includes application-level functionalities.

Hi, Rodrigo!

The only HACK that I can think of is when you get the BYE message, set the dialog timeout to 0, match it against the dialog, and then drop the message. OpenSIPS will behave as if the dialog expired in that moment.

However, you seem to have a flow logic - most likely the Contact header in the BYE is not correct. Could you send  us a trace to help you figure out what the problem is? Also, did you try to validate the message against the dialog[1] and fix it accordingly[2]?

Hi.

Dialogs in my OpenSIPS is programmed to finish after 60 seconds. (timeout = 1 minute).

So, when 2 peers are in a dialog, OpenSIPS sends SIP BYE to both peers, automatically after 60 seconds.

Is it possible to make OpenSIPS send this exact kind of SIP BYE to both peers, before the dialog timeout? I mean, in a configured way (opensips.cfg)?

When OpenSISP sends SIP BYE automatically, both peers receive the SIP BYE correctly.

However, when a peer sends SIP BYE, it reaches the OpenSIPS, but OpenSIPS is unable to forward this SIP BYE. Due to some unknown reason, in this moment there is no open socket to communicate with such peer. That is why I would like to make OpenSIPS send 'its own' SIP BYE, and see if such idea will simulate a normal situation, until I discover why there is a socket problem.

Any hint will be very helpful!

Best regards.
