[OpenSIPS-Users] locally generated replies

[Bogdan-Andrei Iancu]

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.
