This ACK is wrong. Note that the the RURI is opensips itself hen it should be 
the Contact received in the 200 from Asterisk:
  Contact: <sip:xxx at asterisk-ip>

The ACK for a 200 is an *in-dialog* request so it must be setnt to the proxy 
(since it did loose-routing by adding Record-Route header) and the RURI must 
be the final destination.

SIPp doesn't handle corretly this case, I already tested it time ago. You must 
to improve your SIPp scenario and set in the ACK RURI the Contact received in 
the 200. That's all.
