Issam,

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
http://kamailio.org/docs/modules/5.0.x/modules/mohqueue.html#rpc.debug).
This will tell you how mohqueue processes the messages.

Feel free to write back again but I may not be available for another week.

Bob
