NOOB QUESTION: How do i make a outbound call using asterisk?

Hi, I have set up my first asterisk system as per O’reillys guide. I have an external SIP provider and have entered their details into the sip.conf. I am testing this out by making calls to my mobile phone and i am getting a few error messages. I have included the details of what i get below along with my configuration. FOr now I have hard coded my own mobile number in the extension just to test it out. It has been blacked out below. Looking at my telecube console it says that this extension is both active and online. I am running this via virtual box. Any help would be greatly appreciated.

What is returned when i call my mobile phone number:(verbose 4; debug 4)
