At kphone, your configuration must be as the following:
Full Name: <Your name if you wish> User Part of SIP URL: <username, ex 11112> Host Part of SIP URL: <IP or domain name of your server. ex: mysipserver.com> Outbound Proxy (Optional): <NOTHING MUST BE PUT HERE> Authentication Username: <if you have , use username for auth. ex: 11116> q-valeu between 0.0-1.0: <NOTHING>
After configuring all the steps, click the "Auto Register" option then click OK. Kphone you tell you that this configuration only works after re-opening the program. Close it and re-open. If everything goes fine, you will only be ask for the password.
