This is not the function of fix_nated_contact(). Have a look at a 
add_rcv_param(): 

http://kamailio.org/docs/modules/4.2.x/modules/nathelper.html#nathelper.f.add_rcv_param 

Someone might correct me if I'm wrong, but I believe the problem with 
the ;received approach is that it's only useful for registrations, since 
only the registrar module has a provision that allows it to be used 
automatically. So, for larger applications outside of registration, you 
should take a look at the new add_contact_alias() / handle_ruri_alias() 
facility: 

http://kamailio.org/docs/modules/4.2.x/modules/nathelper.html#nathelper.f.add_contact_alias
