citytelecom Posted June 1, 2012 Report Share Posted June 1, 2012 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? Peter Baker Quote Link to comment Share on other sites More sharing options...
