POTS Replacement:
The Complete Guide

Copper landlines are being shut down. AT&T begins decommissioning in June 2026. If your business depends on analog lines for phones, alarms, elevators, or fax — you need a plan now.

AT&T Copper Shutdown begins June 2026. As of October 2025, AT&T stopped accepting new copper orders in 19 states. Businesses now have as little as 90 days notice before their lines go dark. Don’t wait for the letter.

What is POTS & what’s at risk?

POTS stands for Plain Old Telephone Service — the traditional copper landline network that has powered business communications for decades. It also powers critical infrastructure that most businesses don’t think about until it stops working.

Systems that depend on copper lines:

  • Fire alarm panels & monitoring systems
  • Elevator emergency phones
  • Security alarm dialers
  • Fax machines & analog modems
  • POS terminal backup lines
  • Gate access & entry systems

Why is this happening now?

The FCC has been streamlining copper retirement rules since 2019, and in March 2025 accelerated the process significantly — reducing notice requirements from 180 days to just 90 days and removing requirements for carriers to offer standalone voice alternatives.

AT&T spends nearly $6 billion annually maintaining its aging copper network for fewer than 3% of customers. The financial math is clear — copper is going away, and it’s going away fast.

Some businesses are seeing POTS line costs spike to $2,700+ per line per month as carriers use price pressure to force migration.
