3. X-Lite (including FWD X-Lite, both in SIP mode). Select Menu/System Settings/SIP Proxy/Default. Make sure it is 'Enabled', enter your SIP user id prefix (e.g. mark) in the 'User Name' and 'Authorization User' fields. Enter 'Password' (the password is the same as the RealTunnel password when using our realsip.com SIP domain). You may not have to enter password on all SIP servers. Set 'Domain/Realm' to your desired SIP domain e.g. realsip.com.

4. Custom SIP client (i.e. other SIP client)

1. In your SIP endpoint, configure the RealTunnelTM client as a SIP proxy. I.e. configure "outbound proxy" address in the SIP client to the IP address of your local PC and e.g port 5061 (UDP). This port must correspond with the port configured in the RealTunnelTM client explained in the introduction above. If this port is taken by another application, change port number in both applications.
