Never trust anything a device sends to kamailio :)

If you are using a config close to default your problem is in route[NATDETECT]
        if (nat_uac_test("19")) {
                if (is_method("REGISTER")) {
                        fix_nated_register();
                } else {
                        add_contact_alias();
                }

http://www.kamailio.org/docs/modules/stable/modules/nathelper.html#idp1806784
=========================
5.4.  fix_nated_register()

The function creates a URI consisting of the source IP, port, and protocol and 
stores the URI in an Attribute-Value-Pair. The URI will be appended as 
"received" parameter to Contact in 200 OK and registrar will store it in the 
received cloumn in the location table.

Note: You have to set the received_avp parameter of the nathelper module and 
the registrar module (both module parameters must have the same value) to use 
this function.

This function can be used from REQUEST_ROUTE. 
=========================

If that brings no relief take a look at the third argument for save
http://www.kamailio.org/docs/modules/stable/modules/registrar.html#idp1975072
If you can construct a correct URI supply it to save.
