Record-Route indicates the path that _sequential requests_ should take. Sequential requests are requests within a dialog, such as a reinvite (as opposed to an initial INVITE), a BYE, UPDATE, etc.

Sequential requests have a Route: header and a To tag field.

Sorry I didn't write what I meant. But the point was that the OpenSIPs on 41.221.230.60 is not doing any Contact mangling.
