I'd like to take this opportunity 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.
I've done some testing on the line and can see no reason why you should be experiencing this issue. 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 in a known working line. Once you are able to eliminate the phone, the next step would be to book a technician to call out and investigate further for you.
I'll send you a private message in order to get things moving once you've been able to eliminate the phone. Please look to the top left of this page where you'll see a red envelope icon, click on this and you'll see my message.
