<div dir="ltr"><div>Issam,</div><div><br></div><div>Sorry, it is vacation season and I haven't been able to get back to you on this. I recommend that in addition to analyzing the SIP trace you also enable mohqueue debugging and look at the Kamailio logs (see <a href="http://kamailio.org/docs/modules/5.0.x/modules/mohqueue.html#rpc.debug">http://kamailio.org/docs/modules/5.0.x/modules/mohqueue.html#rpc.debug</a>). This will tell you how mohqueue processes the messages.</div><div><br></div><div>Feel free to write back again but I may not be available for another week.</div><div><br></div><div>Bob </div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jun 14, 2017 at 12:36 PM, Issam <span dir="ltr"><<a href="mailto:ihambouz@gmail.com" target="_blank">ihambouz@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div><div><div>Hello Robert,<br><br></div>Thank you for your response.<br><br></div>Point 1 is crystal clear, just needed such confirmation.<br><br></div>Point 2: Looking at the below trace, can't find anything wrong (except the 404 response for BYE at the end). Moreover, it looks to me that the INVITE gets positively completed, taking into account the 200 OK + MOH getting played. Yet, the mentioned error appears after 4-5 seconds, at the same moment the call gets removed from mohqcalls table .. as for the MOH, it keeps playing as expected.<br><br></div><div>Hints and comments
