This is fine. The Contact tells the server where to send incoming 
INVITEs in the case of a REGISTER. If it wasn't your address then the 
server wouldn't really know where to send incoming calls. If you need it 
to be a public IP address then NAT settings can be set on the transport.

The domain in the From header can be set using from_domain on the endpoint.

It would also be useful to provide the configuration, minus passwords, 
and an example of a working SIP INVITE from another machine...
