gateway and in certain scenarios only.

I'd like to insist on this. The problem is there: the provider SHOULD send
the 
BYE (in-dialog BYE containing "Route" header) to the URI indicated in 
the "Contact" header that OpenSer sent to provider.
But instead of that, the provider sens the BYE to a wrong URI 
(sip:test at 78.45.146.34).

Could you do a ngrep when a call from PAP2 to other PAP2?
  ngrep -d any -P ' ' -W byline -T -t "$*" udp port 5060
