A landline was typically a phone number that depended on physical copper lines to make and receive voice calls. The advent of VoIP and digital phone lines, alongside the global withdrawal of PSTN infrastructure, has meant that this meaning is shifting. Nowadays the term 'landline' is increasingly used to refer to a number that isn't an 07 mobile or cellular phone number.
