POTS Replacement: What It Is and How It Works

For decades, businesses have relied on POTS (Plain Old Telephone Service)—the copper-wire landline system that’s been the backbone of voice communication. But the era of POTS is coming to an end. Carriers are phasing out these aging networks, and companies are looking for reliable, cost-effective alternatives. That’s where POTS replacement comes in.

How It Works in Simple Terms

      1. A Little Box Gets Installed
          A technician puts in a box about the size of a home Wi-Fi router. Your current phone or alarm line plugs right into it.

  1. It Uses Modern Networks
    Instead of copper wires, that box sends the signal through either the internet or a cell network—just like how a smartphone works.
  2. It Keeps Working in Outages
    These boxes have backup batteries and often two ways to connect, so your emergency lines stay alive during a power or internet outage

Why Switch Now

  • Old Lines Are Going Away: Phone companies are retiring their copper networks. Waiting too long can mean sudden outages or higher bills.

  • Safety Rules Still Apply: Fire alarms and elevator phones must always have a dial tone. POTS replacement keeps you compliant.

  • Saves Money and Headaches: One predictable monthly fee usually costs less than old landline service and maintenance.

Getting Started Is Simple

A provider will:

  • Check how many lines you have and what they’re used for

  • Install the box and battery backup

  • Test everything so your alarms, faxes, or phones keep working

Bottom line: POTS replacement is like moving from an old flip phone to a modern smartphone—but you don’t have to change your equipment. You get the same dependable service, just on a stronger, more future-proof network.
