<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 <u></u><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>

<p>If <u></u><b><u>t</u></b> is just few minutes, let's say 2 minutes, there is no any issue.</p>
<p>However, if <b><u>t</u></b> is bigger, let's say 4 minutes, his issue is present.</p>
<p><br>
</p>
<p>What is happening here? Can someone give some help, please!</p>
<p>Any hint will be very helpful!</p>
