<p>Hi <font style="font-size:11pt" color="#000000" face="Calibri, sans-serif">Bogdan</font>.</p>
<p><br>
</p>
<p>I have just finished studying about some parts of OpenSIPS documentation, mainly about the modules.</p>
<p><br>
</p>
<p>I saw that it is possible to take control of call duration using Call Control,<span lang="en">which</span> is too complex to my simple needings as my projetct doesn't need a charging system, or using DLG_timeout as you well pointed.</p>
<p><br>
</p>
<p>So, in my OpenSIPS script I should do something like this:</p>
<p><br>
</p>
<p> # account only INVITEs<br>
if (is_method("INVITE")) {<br>
<br>
# create dialog with timeout<br>
if ( !create_dialog("B") ) {<br>
send_reply("500","Internal Server Error");<br>
exit;<br>
}<br>
<br>
$DLG_timeout = <some variable with amount of seconds>;<br>
<br>
}<br>
<br>
</p>
<p>However the final user is the one who must define how long a call can exist. Such configuration will be done via a proprietary GUI in my project, any time.</p>
<p>So, I was looking for a way to set 'some variable with amount of seconds' and pass it to OpenSIPS, before starting calls. That is, how can OpenSIPS read a external variable or how to write DLG_timout via MI ? I didn't find a solution.</p>
<p><br>
</p>
<p>Then, my development team has decided to put a new field (X-Timeout) in the SIP INVITE header, configuring it with the desired amount of seconds.</p>
<p>So, in the OpenSIPS script we could read the value from X-Timeout and set it to the DLG_timeout.</p>
<p><br>
</p>
<p>What do you think about this approach? Is it simple to read a header field from SIP INVITE, isn't it? I will take a look in the documentation.</p>
<p><br>
</p>
<p>Any hint or suggestion will be very helpful!!</p>
<p><br>
</p>
<p>Thanks a lot!<br>
</p>

<div><tt>Hi Rodrigo,<br>
<br>
The timeout for a call can be set (in a per-call manner) when the call starts (during re-INVITE) or during any sequential requests (ACK, re-INVITE), etc. See DLG_timeout variable:<br>
<a title="Ctrl+Clique ou toque para seguir o link" id="LPlnk63299" class="moz-txt-link-freetext" href="http://www.opensips.org/html/docs/modules/1.11.x/dialog.html#timeout-pvar-id">
http://www.opensips.org/html/docs/modules/1.11.x/dialog.html#timeout-pvar-id</a><br>
<br>
If you want to tear down the call, use the dlg_end_dlg MI command :<br>

<p>Dear OpenSIPS-Users,<br>
</p>
<p><br>
</p>
<p>A kind of management application in my project must provide an way of a system manager sets the default_timeout for dialogs in our already running OpenSIPS. How to do it?
<br>
</p>
<p><br>
</p>
<p>I was looking for an way of sending a command to OpenSIPS 2.2 to configure it to tear down (hang up) every call after a determined timeout. So I have just read about MI, dialog exported MI functions and dialog exported pseud-variables. What I want is to
configure the default_timeout without having to reset the OpenSIPS.</p>
<p><br>
</p>
<p>However, I didn't find a way of doing that. I was thing about to use mi_fifo and a exported command, but no way.</p>
<p><br>
</p>
<p>Is there a way of controlling the default_timeout for dialogs, while OpenSIPS is running?</p>
<p><br>
</p>
<p>If not, I was thinking about changing the value of timeout column in the table dialog, for each dialog. But, it sounds a bit complicated.</p>
<p><br>
</p>
<p>Any idea?</p>
<p><br>
</p>
<p>Any hint will be very helpful!</p>
<p><br>
</p>
<p>Best regards.</p>
