<br>
The endpoints send the Invite twice (Time 0.000 and Time 0.099),
after that The proxy (opensips) send back a 500 . It seems like
the endpoints consider timed out the first invite and it resend
again.<br>
<br>
My routing flow is:<br>
<br>
1. Check if is an INVITE from a GW ( is_method("INVITE")
&& is_from_gw() ) <br>
2. do a "dp_translate" <br>
3. route to "check_channels" block that is composed in this mode:<br>
<blockquote>
<ul>
<li> Check the available channels , script idea taken from <a
href="http://www.opensips.org/Resources/DocsTutConcurrentCalls">http://www.opensips.org/Resources/DocsTutConcurrentCalls</a></li>
<li> Call the "call_control()" functions as described in
call_cc.txt (attached)</li>
</ul>
</blockquote>
4. call "topology_hidding()" function<br>
5. engage_mediaproxy()<br>
6. call do_routing, and add some helper routes (t_on_branch("2");
t_on_reply("2"); t_on_failure("2");) and call the t_relay() . The
block is attached in helper.txt file.<br>
<br>
<br>
<br>
<br>
Thanks again for your time<br>
<br>
<br>
Regards<br>

<pre wrap="">I analyzed the traces you sent and I'm seeing very weird things on the OnAnswer set:
An endpoint sends an INVITE to the proxy, the proxy sends a 500 and the device acknowledges it with an ACK. Yet the proxy seems to forward the INVITE anyway! As you can see from the response on the BYE request (481) the proxy is confused and so is CallControl.
Can you better describe how you are doing the routing and when do you call call_control in your OpenSIPS script? (an overview, please don't attach a full configuration file).
