I still remember my parent´s home landline from 30+ years ago (long gone) but I have no idea of what is my current one or any other of the many I have had to have over years due to telecoms´ bundles. They are not useful anymore, not even as a resilient second line since they are connected to the same fibre line. It is just a gimmick to extract a few more euros from the consumer.
