"407 proxy authentication required" is a normal message for authentication based providers. When you make an outbound call the provider asks for authentication using this method and the PBX replies with the appropriate credentials. So that is not the problem. You should check your activity log and see what happens after this message.

And make sure the extension you are using to make calls is part of the default group of extensions. Also make sure that you are dialing the numbers in the correct number format as some providers are very specific about that.
