Unable to set up IP Authenticated SIP

Hi,

I am attempting to set up IP Authenticated SIPs on the Snom One.

The Snom One is installed on a LAN with an internal IP address, it has a NAT'd static external address and it is this address to which the SIP authenticates.

I am unable to make an O/G call. This is because the the internal IP is appearing in the header as can be seen from the INVITE:

INVITE sip:902083279088@10.0.0.251;user=phone SIP/2.0

 

10.0.0.251 is the internal address.

 

Can anyone help?
