Good Morning @virgel, thanks for your post on our Community Forums, and a very warm welcome to you!
Sorry to hear of the landline issues. I've looked in the local area, and currently no outages are being flagged.
In the meantime, can you please advise me if you've attempted to try and new handset in the socket for me?
Can you also confirm if the handset is plugged into the master socket or an extension?
We would advise that you try multiple different handsets in the master socket and ensure no other pieces of equipment are connected to the master sockets when testing the line at home
Please advise me if the above has been completed and if required, we can look into this further for you
Kindest regards,
David_Bn
