Telephone lines are used to deliver landline telephone service and Digital subscriber line (DSL) phone cable service to the premises. 

Standard and internet phonelines

The two common types are:

  • POTS (Plain Old Telephone System) Lines: These are analogue lines which allow one call per line. Can be used singly or combined for a multi-line system with a PBX (exchange). It has been reported that BT is planning to transition all of its customers to internet-based voice calls by 2025.
  • VoIP (Voice Over Internet Protocol) – also known as internet telephony, IP telephony, or broadband phone – is a way of making phone calls that doesn’t use a traditional phone line, and instead uses the internet. Usually, one of thre methods will be used: (1) A phone and a VoIP adapter; (2) A computer; or (3) A Smarttphone app. Read more at VoiP pros/cons, choices and information (
