Landline not working intermittently

[Kevin_roberts20]

My landline uses an extension socket in the bedroom (with 2 additional handsets downstairs) with my hub plugged into my master socket by the front door. Both have filters and everything has been fine for over 10 years, however recently I have been unable to make or receive calls more often than not. I have a dial tone but when I dial the number nothing happens. Equally if I call my home number the phone rings but goes dead when I pick up the receiver. I've tried swapping filters around with a spare I had and it worked for a while and then stopped again. I've run a test on the line and it says it's fine and that it's probably the filters. I've ordered a new one but I'm not convinced it will work. Has anyone had a similar issue?

Hi @Kevin_roberts20 welcome to the community, I'm sorry to see you're having issues with your landline. Do you have a test socket that you can connect your phone to? This bypasses the extension wiring which may help to narrow down what's causing this problem.

Thanks for the reply. I haven't taken the face plate off to try the test socket but I did try plugging the landline into the master socket and it worked fine, so I'm not sure if the test socket would help prove anything. At 2 30 today it wouldn't work but later at 5:30 it's fine without changing anything. It would be easier to diagnose if it was just permanently not working!
