Firstly I'd like to welcome you to the forums and say that I'm really sorry to hear that your phone line is not working at the moment, and I'd love to help you out.
I've done some testing on the line, and can see no reason why you should be experiencing this issue, as there are no known local issues, and the line test is clear.
I'd now have to ask if you'be been able to eliminate the phone from being at fault, either by trying another phone on the line, or to try your phone in a known working line. Once you're able to confirm that the phone has been eliminated then the next step would be to arrange for someone to call out and take a closer look at things.
I've sent you a private message in order to get the wheels in motion. Please click on the purple envelope icon at the top right of this page and you'll see my message.
