Thanks for your post and welcome to the community.
Sorry to see that you're experiencing issues with the landline, just to clarify have you checked the cables are securely fastened?
Also is it just a master socket you have or an extension?
Let us know,
it applies to all sockets. There is no dial tone, cannot make calls. I called the landline number and after much delay, the phones ring but the call is not received when the landline is answered
Thanks for the response there,
It looks like we'll need to get a technician out, so we can investigate this further I've dropped you a PM.
The PM will appear within the purple envelope icon.
