 Hi Bogdan,
I'll try to get this info and examine. 
Thanks for the follow up :)

  Hi Pasan,
 
 I doubt that fix_route_dialog() is doing something wrong :D. Maybe there is something wrong with the signaling / cfg. After the call is established, do a "opensipsctl fifo dlg_list <callid>" to see the dialog details as learned by OpenSIPS.
 
 Also post the incoming BYE, to see how does it "fit" to the dialog and what should be the effect of the "fixing".
 
 Regards,

  Hi Bogdan, 
  Yes, that was the theory I had,  And after I remove the fix_route_dialog function it didn't reoccur yet, so I believe fix_route_dialog caused the bad routing in my script I think.

   Hi Pasan,
 
 Have you checked if there is traffic on looping on your OpenSIPS ? maybe 
 due bad routing, OpenSIPS is keep sending to itself some traffic, 
 causing the loops and the load.

Anyhow issue resolved after I removed fix_dialog_route() function which causes  BYE to send to a private ip of a NATed device. I have fix_nated_contact() before create_dialog() function but dialog data seems to have unmodified contact data which I believe is fixed in 2.4 as you mentioned.
