Test the setup, but I had no success, although fix_nated_register ()
seems to work correctly, I see this in the amount of $avp(i:42),
but in the "contact"table "location " The port is duplicate.
What can be causing this problem?
Check that:
1) you are not receiving (in REGISTER) an already bogus contact (with 2
ports)
2) you are not doing by mistake another fix_nated_contact in other parts
of the script (not REGISTER related blocks, maybe)

Something is wrong here. Normally, if using only fix_nated_register(),
you should have:
- private contact (as received in REGISTER) in "contact" column
- public NAT ip (src of REGISTER) in "received" column
I your case you have only a "contact" value which is public :-/.....It
looks like your fix_nated_register() has no effect, but a
fix_nated_contact() does (maybe in other parts of the script).
(see below)

if (!db_check_to())
{
sl_send_reply("403","Forbidden auth ID");
exit;
}
if (!save("location"))
sl_reply_error();

}
and be 100% sure you do not call any other fix_nated_contact() like
functions for this REGISTER (maybe in some other scripting block, before
register processing).
