The copper phone network has powered American businesses for over a century. AT&T is switching it off π
Starting June 30, AT&T begins the first major wave of copper wire center decommissioning, with hundreds of centers going dark nationwide and more shutdowns already scheduled into late 2026, 2027, and a stated goal of retiring nearly all copper by 2029.
Here's what a lot of business owners don't realize: when your wire center is decommissioned, every POTS (plain old telephone service) line it carries goes dead, permanently. No forwarding. No grace period. Under current FCC rules, carriers owe you only 90 days of notice before the line goes silent.
This matters more than most teams realize, because copper often runs quietly in the background: fire alarm panels, elevator phones, security systems, fax lines, and the main business number your customers have called for years.
The businesses getting ahead of this aren't scrambling. They're moving to VoIP now, with clearer calls, lower monthly costs, and features copper never offered: voicemail-to-email, call forwarding, and the ability to answer from anywhere.
Cardinal Technology Solutions handles the full migration. We audit which of your lines run on copper, design the right VoIP setup, and support it long after the switch.
The deadline is set, but the move is straightforward when you have the right partner π‘οΈ
