Plain Old Telephone Service (POTS) lines have long supported critical business functions such as fire alarms, elevator phones, and backup communications. Those days, however, are numbered.
Carriers have pulled back hard on copper investment, resulting in slower repairs, thinner support, and mounting uncertainty for any business still relying on legacy lines. Recent industry reports show that repair times and support quality for POTS lines have deteriorated significantly.
This article examines the current decline in POTS reliability and how SOLUS helps organizations migrate to modern alternatives with minimal disruption. SOLUS delivers a structured, low-risk transition that improves reliability and provides long-term cost predictability.
The Current State of POTS Lines
POTS still handles essential functions in thousands of buildings, but carriers are rapidly moving away from supporting the infrastructure. In the past 12 months, multiple providers have filed notices to discontinue legacy voice services in various regions.
AT&T
AT&T is dismantling its copper network on a national scale, with a full shutdown targeted for 2029. This multi-year transition includes aggressive wire center closures, forcing mandatory migrations to fiber or wireless alternatives.
Key transition milestones and news include:
- New Order Freeze: As of October 15, 2025, AT&T stopped accepting new orders, moves, or changes for analog POTS lines across 19 states.1
- Statewide Discontinuance Schedules: AT&T has filed a string of Section 214 discontinuance notices with the FCC. Illinois customers, for instance, have already received termination dates of March 15, 2027, or later.2
- Regulatory Battles: In May 2026, AT&T sued in federal court in California to override state Carrier of Last Resort rules that had been blocking the company from shutting down 360 copper wire centers. The outcome will shape how fast, and how forcefully, this transition plays out elsewhere.3
Carrier Support Degradation and Its Impact
Carriers have cut technician headcount and spare-parts inventory for copper lines, and it shows. Repair windows that used to be measured in hours are now stretching into days as resources shift toward fiber and wireless buildouts. A 2025 analysis noted that “mean time to repair for legacy copper services has increased substantially as providers shift resources to fiber and wireless.”4
The takeaway? As AT&T and other carriers retire copper loops, customers will see longer outages and fewer repair options.5 This degradation raises both operational risk and maintenance costs for organizations still dependent on POTS.
Business and Operational Risks
Facilities and IT teams are increasingly the ones fielding the fallout when an alarm circuit or elevator phone goes dark and the carrier can’t get someone out for days. Parts are harder to source, and repairs cost more. The lines that matter most (alarms, emergency communications) are often the ones carriers care least about keeping alive.
Regulatory and Compliance Considerations
The FCC has permitted copper retirements provided adequate replacement options exist. However, many industries still require reliable circuits for alarms and emergency communications. Delaying migration can create compliance exposure as carrier support continues to decline.
Key Rulings and Orders
| Action | Year | Impact |
Technology Transitions Order | 2015 | Permitted AT&T and others to conduct IP transition trials |
| FCC Order 19-72 | 2019 | Allowed carriers to retire copper/POTS infrastructure with limited notice |
| Section 214 Forbearance | ongoing | Reduced requirements for carriers to maintain legacy copper networks |
| Eliminate Carrier of Last Resort (COLR) | various | States began removing obligations to provide basic phone service |
Key Drivers Behind Agency Decisions
- Declining POTS subscriptions (dropped from ~180M to under 30M lines)
- High maintenance costs of aging copper infrastructure
- Broadband & wireless seen as modern equivalents
- Industry lobbying from AT&T, Verizon, and others
- Push toward Universal Broadband replacing Universal Telephone Service
Why Traditional Replacement Options Fall Short
The instinct is often to grab a consumer VoIP adapter or a cellular failover box and call it done. In practice, those options weren’t built for business-critical use. They struggle with power-fail operation, and reliability under load isn’t their strong suit. Multiply that across a dozen sites with a dozen different point solutions, and now the problem is a patchwork of systems that nobody can manage consistently.
How SOLUS Addresses These Challenges
SOLUS provides a comprehensive migration service that combines technology, process discipline, and ongoing support. Key advantages include centralized management across locations, proactive monitoring, and predictable long-term costs.
We enable organizations to move away from declining POTS infrastructure while gaining modern monitoring and reliable support.
Recommended Migration Approach
SOLUS recommends a phased strategy:
- Assessment – Inventory all POTS lines and classify critical versus non-critical services.
- Prioritization – Address alarm, elevator, and security lines first.
- Pilot – Validate replacement solutions at selected sites.
- Full Migration – Execute coordinated cutovers with fallback plans.
- Ongoing Management – Transition to SOLUS monitoring and support.
Conclusion
POTS line obsolescence is an active operational issue. As carrier support continues to degrade, organizations that delay action face rising risk and cost. SOLUS offers the expertise and methodology needed to transition successfully to modern alternatives.
Organizations should contact SOLUS to begin an assessment of their current POTS environment.
