BYE sip:15125551234 at 62.175.182.141:5060 SIP/2.0.
Record-Route: <sip:195.62.163.131;lr;ftag=BDA2FF96-481D6819>.
Route: <sip:62.175.182.141;r2=on;lr;ftag=1c2145666146;did=fe6.729dae35>,
<sip:10.10.65.141;r2=on;lr;ftag=1c2145666146;did=fe6.729dae35>.

OpenSIPS receives the BYE, it see itself in the first Route (so we are
doing loose route) and since it's itlesft if delete it and looks for
the next Route that is:
  sip:10.10.65.141

Yeah.

It's complex. You could try to add the sent Contact URI as a
Record-Route parameter so it should get back untouched (but in a Route
header). Then you can replace the RURI adress with that URI.

But it's dirty.... :(
