Verizon’s phase-out of legacy PRI, T1, and analog POTS lines is accelerating disruptions for DC-region organizations still tied to these outdated TDM network services. As of early 2026, unsuspecting businesses face skyrocketing bills or total cutoffs, but TCI offers a seamless path to modern IP solutions that enhance reliability and cut costs.

Verizon’s Phase-Out Timeline

The shutdown is underway, hitting Maryland, Virginia, and DC hard.

• No new orders for PRI, T1, or POTS have been accepted after September 1, 2025.
• Physical service withdrawals began November 1, 2025, with ongoing disconnections.
• Bills are doubling for holdouts, with full retirements expected by 2026-2027 in many areas.

This shift to IP prioritizes fiber and cloud, leaving legacy service users vulnerable to outages and compliance risks in regulated sectors like government, finance, and healthcare.

Risks of Delaying Migration

Sticking with old services spells trouble for decision makers.

• Downtime Threats – Forced cutoffs disrupt critical ops like alarms, elevators, and 911 access.
• Rising Costs – Some Verizon customers are reporting 100% bill increases.
• Security Gaps – TDM lacks modern encryption, exposing data in high-stakes environments.

Taking proactive action now will prevent chaos and position your team for growth.
