[Users] Rewriting Contact HF port

[Justin Pearce]

Hi Bogdan,

I knew that Nathelper did some rewriting, but the circumstances required
that the thing record the private IP and a certain known port instead of
the public IP as a contact address (using fix_nated_register() to save
the other address). I wound up borrowing the code from the Nathelper
module and modifying it to accept a port argument and made it a separate
module. This way, it only rewrote the port and not left everything else
untouched.

Thanks.

Hi Justin,

if you need save(location) to save as "received" a custom uri, you just 
need to set an avp with the uri you need to be saved. See:
    http://openser.org/docs/modules/1.1.x/registrar.html#AEN211
It's exactly what nathelper does.

regards,
bogdan
