<tt>Hi Ben,<br>
<br>
The issue is a bit more complex. When generating the BYE requests,
the dialog module triggers the event of call terminated when it
gets back the first final reply (to any of the BYEs). And ACC
module generates the CDR when the dialog is terminated.<br>
<br>
So, the second BYE (which probably ends with timeout) ends in
failure route (and set the acc extra) *after* the call was
terminated and the CDR generated.<br>
<br>
Regards,<br>
</tt>

<p>I think you should take care of this on your gateway. For
example, using freeswitch or asterisk, you can check for rtps,
and when the other end stops sending rtps for 30 seconds
(configurable) it will tear down the call properly.
<o:p></o:p></p>
<p>Unless you're using a rtp-proxy with opensips which can do
this (most can), that's the way to do this. Anything else is
just duct-taping.<o:p></o:p></p>
<p>My opinion after 20 years on voip.<o:p></o:p></p>
<p>Hope that helps.<o:p></o:p></p>

use the dialog timeout mechanism to terminate long

disconnected, but we did not receive or process the
disconnect, due to a malformed BYE or a network
disruption. In these cases, when the Dialog timeout is
reached and OpenSIPS generates a BYE to both parties,
they will respond with a 481.<o:p></o:p></p>
