If you set 'nat=yes' in the sip.conf peer entry for that device in
Asterisk, Asterisk will reply to the IP address and port number the
REGISTER request was received from, not the address in the Contact
header provided in the request itself. It will also record this address
and port number as the location of that peer for future INVITE messages
to be sent to it.
