I did some thinking on this matter and I think it might not be the case. 
If you have a PATH hdr stored on the contact record, means that there is 
a proxy (minimum) between the register and the UAC. Now, we have to cases:
    - that proxy has public address - in this case no received is set, 
so there is no problem
    - that proxy has private address and advertise it - in this case 
there is an received and for sure you want to use it to get to that 
proxy (and not to use the private advertised addr).

please correct me if I'm wrong about something.
