Yes, double RR works fine. As you see in the BYE:
BYE sip:83.136.32.83:5060;r2=on;ftag=a613b273;nat=yes;lr=on SIP/2.0.
Route: <sip:83.136.32.83:6060;r2=on;ftag=a613b273;nat=yes;lr=on>, 
<sip:klaus at 84.20.167.143:7404>.

both RR are present (Cisco is a strcit router, thus one RR is int eh 
request URI, the second one is in the Route header).

Should openser change the sending socket according to the second Route 
URI? I've also tried with a loose_router as callee and it again does not 
work.
