We are renovating the living room, including taking out the concrete floor. There is an old landline underneath/at the wall which we no longer use (the modem/router is connected via a different cable).
Can we just “cut off” the landline and bury the remaining cable under a new concrete floor, or do we need to have it properly removed by KPN, in case some future owners want to have a landline again?
Thank you and best regards,
Cathrin
