<p>Hi Răzvan.</p>
<p><br>
</p>
<p>I'm still investigating the problem.</p>
<p>Now I'm using the<tt>'Pp' flag to create_dialog()</tt>, as you had suggested. In this case I can see that OpenSIPS sends SIP OPTIONS to the 2 peers and they respond with SIP 500 "<i>Unhandled by dialog usages</i>". It is ok to a ping purpose, isn't it? That
is, even if the response is SIP 500, OpenSIPS will know that the peer is online. Ok?</p>
<p><br>
</p>
<p>One thing that let me curious is the log below (that rises even using 'Pp' flag to create dialogs):</p>
<p><br>

</p>
<p><br>
</p>
<p>The problem here exists when user B sends SIP BYE to user A. B sends it to the contact
<font face="Calibri,Arial,Helvetica,sans-serif" size="3" color="black"><span style="font-size:12pt;" id="divtagdefaultwrapper"><font size="2"><span style="font-size:10pt;">user_A@192.168.0.101:57985</span></font></span></font>. However, this contact is not
known by OpenSIPS and then the proxy complains with such log. OpenSIPS does know just the contact in the location table, doesn't it?</p>
<p><br>
</p>
<p>In table location the contact of user A is "<font face="Calibri,Arial,Helvetica,sans-serif" size="3" color="black"><span style="font-size:12pt;" id="divtagdefaultwrapper"><font size="2"><span style="font-size:10pt;"><span style="color: rgb(0, 111, 201);"><span style="color: rgb(255, 0, 0);">user_A</span></span><span style="color: rgb(255, 0, 0);">@</span><span style="color: rgb(255, 0, 0);">127.0.0.1:36427</span></span></font></span></font>".
But, during the dialog, A sends a SIP UPDATE to B. And such UPDATE has the contact "<font face="Calibri,Arial,Helvetica,sans-serif" size="3" color="black"><span style="font-size:12pt;" id="divtagdefaultwrapper"><font size="2"><span style="font-size:10pt;"><span style="color: rgb(0, 111, 201);"><span style="color: rgb(255, 0, 0);">user_A</span></span><span style="color: rgb(0, 111, 201);"><span style="color: rgb(255, 0, 0);">@192.168.0.101:57985</span></span></span></font></span></font>"
when it arrives in B. Softphone for user B and OpenSIPS is running in the same hardware, as I told before, with
<span>IP = 192.168.0.101</span>. So, I suspect that UAC B decides to send SIP BYE to "<font face="Calibri,Arial,Helvetica,sans-serif" size="3" color="black"><span style="font-size:12pt;" id="divtagdefaultwrapper"><font size="2"><span style="font-size:10pt;"><span style="color: rgb(0, 111, 201);"><span style="color: rgb(255, 0, 0);">user_A</span></span><span style="color: rgb(0, 111, 201);"><span style="color: rgb(255, 0, 0);">@192.168.0.101:57985</span></span></span></font></span></font>"
due to that contact found in SIP UPDATE.</p>
<p><br>
</p>
<p>It seems that UA A sends SIP UPDATE just when it and OpenSIPS is running in the same hardware. But I'm not sure...</p>
<p><br>
</p>
<p>Should I fix the contact in the SIP UPDATE before relaying it? Is it possible by means of the opensips.cfg file script to fix the contact in the SIP UPDATE?</p>
<p><br>
</p>
<p>Or should I fix the SIP BYE request when it arrives in OpenSIPS, before the proxy to investigate if the contact is in table location?</p>
<p><br>
</p>
<p><br>
</p>
<p>Any hint will be very helpful!!</p>
<p>Thanks a lot!</p>

<div><tt>Hi, Rodrigo!<br>
<br>
Most likely A closes the connection to OpenSIPS. You can check that by tracing the communication between A and OpenSIPS.<br>
In order to solve that, make sure that the TCP keepalive[1] is enabled. Also, you can use the dialog pinging[2] feature ('Pp' flag to create_dialog()) to keep the dialog connections open.<br>

<div>Dear OpenSIPS users,<br>
<br>
<br>
In my hardware, with IP = 192.168.0.101, I have OpenSIPS and softphone A. Thre is softphone B also, in another hardware.<br>
<br>
A calls B.<br>
B accept the call.<br>
After <b><u>t</u></b> minutes...B hungs up the call.<br>
<br>
In this moment, A enters in a wrong state, because OpenSIPS reports a problem and probably due to it the proxy doesn't communicate with softphone A in such moment. So, my softphone A considers that the call is not ended.<br>
<br>
See what OpenSIPS reports in this moment:<br>
