Firstly I'd like to welcome you to the forums, it's always nice to see a new face. I'm really sorry to hear that your phone line is not working at the moment, and I'd really like to help you out.
I've done some testing on the line, and can see no reason for you to be experiencing this fault, so I'd now have to ask if you've been able to eliminate the phone from being at fault. Either by trying another phone on the line, or by trying your phone on a known working line. I ask this as the next step would be to arrange a technician to call out and take a closer look.
I've sent you a private message in order to get things moving, once you can confirm that the phone has been ruled out. Please look to the top right of this page where you'll see a purple envelope icon, click on this and you'll see my message.
