<div>Hi. Răzvan.<br>
<br>
Thanks to your support, I have found the issue, after some weeks of tests! Now I need to discover how to fix it or a workaround.<br>
<br>
The problem is:<br>
<br>
<br>
Peer A and peer B is connected to the OpenSIPS (OpenSIPS is behind a NAT with public IP = 111.111.240.71). A is in the same hardware as OpenSIPs and B is in another machine. So, OpenSIPs has:<br>
<br>
Connection A :: ID=1 Type=tcp State=0 Source=127.0.0.1:32908 Destination=127.0.0.1:5060 Lifetime=1970-01-02 05:26:31<br>
Connection B :: ID=2 Type=tcp State=0 Source=111.111.240.71:55229 Destination=192.168.0.101:5060 Lifetime=1970-01-02 05:29:50<br>
<br>
When A calls B, the 'contact' in SIP INVITE has Source=127.0.0.1:3290.<br>
When B answers with SIP OK, A sends a SIP UPDATE. This UPDATE has a 'contact' with a new value: Source=111.111.240.71:57186. So, OpenSIPS has:<br>
<br>
Connection A':: ID=1 Type=tcp State=0 Source=127.0.0.1:32908 Destination=127.0.0.1:5060 Lifetime=1970-01-02 05:33:43<br>
Connection B:: ID=2 Type=tcp State=0 Source=111.111.240.71:55229 Destination=192.168.0.101:5060 Lifetime=1970-01-02 05:29:51<br>
Connection A":: ID=3 Type=tcp State=0 Source=111.111.240.71:57186 Destination=192.168.0.101:5060 Lifetime=1970-01-02 05:29:51 (new socket to A)<br>
<br>
However, the new socket between A and OpenSIPS expires in 30 seconds.<br>
Then, when B sends SIP BYE, OpenSIPS tries to forward such SIP message to Source=111.111.240.71:57186, which is expired.<br>
<br>
Peer A and B use ICE.<br>
I would like to fix this issue by means of the OpenSIPS script, to avoid changing the client's code.<br>
Could you suggest me some idea?<br>
<br>
Any hint will be very helpful!<br>
Best regards.<br>
<br>
P.S.: I'm using validate_dialog, but not fix_route_dialog() yet. Could this las function be the solution?</div>

<b>Assunto:</b> Re: [OpenSIPS-Users] How to make OpenSIPS send SIP BYE, by configuration, , before dialog timout?</font>
<div> </div>
</div>
<div><tt>Hi, Rodrigo!<br>
<br>
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.<br>
<br>
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]?<br>

<p>Hi.</p>
<p><br>
</p>
<p>Dialogs in my OpenSIPS is programmed to finish after 60 seconds. (timeout = 1 minute).</p>
<p>So, when 2 peers are in a dialog, OpenSIPS sends SIP BYE to both peers, automatically after 60 seconds.</p>
<p><br>
</p>
<p>Is it possible to make OpenSIPS send this exact kind of SIP BYE to both peers,
<span>before the dialog timeout? </span>I mean, in a configured way (opensips.cfg)?</p>
<p><br>
</p>
<p>When OpenSISP sends SIP BYE automatically, both peers receive the SIP BYE correctly.</p>
<p>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.</p>

<p>Any hint will be very helpful!</p>
