doesn't use the 'received' parameter and it forwards to the RFC1918 IP
address. The initial INVITE from FreeSWITCH has the following headers:

To: <sip:1001@192.168.1.200:5063>
Route: <sip:1.2.3.4>;lr;received=sip:5.6.7.8:5063

Is there any possibility that your Kamailio config strips Route headers
from initial invites? The stock config ships this way.
