free calls to the US and Canada
earthcaller
1. Visit www.earthcaller.com with internet explorer (doesn't work with firefox) 2. It will prompt you to download a small ActiveX component. Accept it. 3. Dial a US/Canada Number - you can try the echo test number I set up 2062035600 . watch out for any leading or trailing spaces as then it will say it is not a US number.
Once you click connect you can see the following messages.
Registering to SIP Proxy. Dialing… Trying to register. Registered successfully. Response: Trying. Response: Session Progress. Success to connect.
