If the BYE from providers arrives correctly to OpenSIPS it means that
loose routing is working correctly.
When OpenSIPS receives that in-dialog request (BYE) it must route it
to the address indicated in RURI. What is that RURI?

Note also that the RURI in the BYE is the URI in the Contact of the
INVITE, and if there NAT issues the proxy must change
(fix_natted_contact) that Contact and replace the private IP:port with
the received IP:port.

So, show a capture to find the problem.
