You mean a Record-Route? If so I don't understand what the problem is
 (you have an extra RR in the ACK which will be ignored).
 If you want to avoid it, make sure record_route() is not called for
 ACKs (if (method!="ACK") { record_route(); } ).
If is really a Route then please dump the sip traffic before and after
leaving ser and post the bad call and the bad ACK.
