A proxy cannot interfere with the ACK part - the acknowledgment is done between end parties.<br><br>If the ACK is missing (in an established dialog), the callee party (according to RFC) must send a BYE (when finishing the 200 OK retransmission) to the caller. This is something your callee doesn't do.<br><br>A simple work around is to use the dialog timeout in opensips:<br> 1) at INVITE time, when dialog is created, set a 5 seconds timeout (dialog will be terminated by opensips, with BYE, in 5 secs after being established - do not forget to set the BYE_ON_TIMEOUT flag)<br> 2) at ACK, before loose_route() set a new timeout to some long, long (3 hours?) value.<br><br>So, if the ACK will mis, the 5 sec timeout will kick in and terminate the dialog; otherwise, opensips will prelong the dialog on ACK time.<br><br>Regards,<br>Bogdan<br><br>On 04/28/2011 03:06 PM, Denis Putyato wrote: <o:p></o:p></p><p class=MsoNormal><span lang=EN-US>Hello!</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US>I noticed that cdr_flag in acc modules marks dialog for accounting as answered even there was no ACK on 200 OK.</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US>As a result, I have acc record which has a big duration and status 200 OK.</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US>Thank you for any help.</span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US> </span><o:p></o:p></p><p class=MsoNormal><span lang=EN-US> </span><o:p></o:p></p><pre> <o:p></o:p></pre><pre> <o:p></o:p></pre><pre>_______________________________________________<o:p></o:p></pre><pre>Users mailing list<o:p></o:p></pre><pre><a href="mailto:Users@lists.opensips.org">Users@lists.opensips.org</a><o:p></o:p></pre><pre><a href="http://lists.opensips.org/cgi-bin/mailman/listinfo/users">http://lists.opensips.org/cgi-bin/mailman/listinfo/users</a><o:p></o:p></pre><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><br><br><br><br></span><o:p></o:p></p><pre>-- <o:p></o:p></pre><pre>Bogdan-Andrei Iancu<o:p></o:p></pre><pre>OpenSIPS eBootcamp - 2nd of May 2011<o:p></o:p></pre><pre>OpenSIPS solutions and "know-how"<o:p></o:p></pre><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><br><br><br><o:p></o:p></span></p><pre>-- <o:p></o:p></pre><pre>Bogdan-Andrei Iancu<o:p></o:p></pre><pre>OpenSIPS eBootcamp - 2nd of May 2011<o:p></o:p></pre><pre>OpenSIPS solutions and "know-how"<o:p></o:p></pre></div></body></html>
