I'd like to start by welcoming you to the forums, and say that I'm really sorry to hear that your phone line is not working at the moment.
Thank you for letting me know that your phone works on another line, as this really helps.
I've done some testing on your line, and can see no reason why you should be experiencing an issue, there are no known local faults, and your line does not show any errors.
So I'd now like to look towards booking a technician to call out and investigate further for you. I'll send you a private message so that we can get things moving with this. Please look to the top right of this page where you'll see a purple envelope icon, click on that and you'll see my message.
