Hi @ Edddddd,
Welcome to the forum page and thanks for posting this on here.
Sorry to hear that you're having some issues with your landline but we can certainly look into this for you.
When someone tries ringing you is there a normal dial tone at all?
Can you ring out on the landline? Is the sound all okay on that or is it silent?
Are all the wires all okay to the landline as this can also cause some issues
Please do let us know as we are more than happy to help
Thanks
