Replace Legacy Copper Lines Before the Carriers Do It for You
The nationwide copper POTS network is being decommissioned. Carriers are raising rates, degrading service, and discontinuing support for plain old telephone service lines — leaving enterprises to find alternatives for alarms, elevators, fax machines, gate systems, and analog voice. RLM helps you audit, plan, and migrate every POTS line before the decision is made for you.
What RLM Delivers on POTS Replacement
POTS replacement is not a single technology — it's a migration strategy that matches the right alternative to each use case. RLM evaluates your entire analog footprint, recommends the appropriate replacement technology for each line, and manages the transition from procurement through cutover.
Fax & Modem Compatibility
Fax machines, credit-card terminals and older modems are the analog devices most likely to fail over a digital replacement. Test the specific devices on the specific replacement technology before committing to a site-wide cutover.
POTS Line Inventory & Assessment
We audit every copper line across your locations — identifying what each line serves (voice, fax, alarm, elevator, gate, point-of-sale), its current carrier and cost, contract status, and regulatory requirements. Most organizations discover 20-40% more POTS lines than they knew they had.
Fixed Wireless & LTE Replacement
For alarm panels, elevator phones, gate access, and other low-bandwidth analog endpoints, cellular fixed wireless adapters provide a drop-in replacement that eliminates the copper dependency entirely. We evaluate carrier coverage at each site and recommend the right device and plan.
SIP Trunking & Hosted Voice
For locations with active voice traffic, SIP trunking replaces copper POTS lines with IP-based voice over your existing broadband connection. We design the SIP architecture, select the provider, and manage number porting — including complex multi-location deployments with local number preservation.
Fiber-Based Voice Alternatives
Where fiber is available, managed voice services over fiber provide the highest quality and reliability. We evaluate fiber availability at each site and design hybrid architectures that combine fiber-based voice for primary locations with cellular backup for remote or low-traffic sites.
Regulatory & Life-Safety Compliance
Elevator phones, fire alarm panels, and building security systems often have specific regulatory requirements for line monitoring and backup power. We ensure every replacement meets local fire code, AHJ requirements, UL 2524 certification standards, and E911 obligations.
Managed Cutover & Project Management
POTS replacement across dozens or hundreds of locations requires coordination between carriers, equipment vendors, building management, and alarm monitoring companies. RLM manages the full project — scheduling, provisioning, testing, number porting, and carrier disconnect coordination.
How We Approach POTS Replacement
A structured migration process that starts with understanding what you have, matches the right replacement technology to each use case, and manages the transition without disrupting the services your business depends on.
POTS Line Audit & Discovery
We pull carrier records, walk sites, and document every active copper line — what it connects to, who depends on it, what it costs, and when the contract expires. This audit typically uncovers forgotten lines, billing errors, and lines paying for services that have already been decommissioned.
Technology Matching & Design
Each POTS line maps to a specific replacement technology based on its use case, bandwidth requirements, regulatory constraints, and site infrastructure. We design the target architecture — cellular for alarms and elevators, SIP for voice-heavy locations, fiber where available, and hybrid where needed.
Provider Selection & Procurement
We evaluate and negotiate with replacement providers across cellular, SIP, and fiber — comparing coverage, reliability, pricing, and contract terms. RLM's provider relationships secure pricing and terms that aren't available through direct engagement, often reducing total line costs by 40-60%.
Phased Migration & Cutover
We manage the migration in coordinated phases — provisioning replacement services, scheduling cutovers during maintenance windows, coordinating with alarm monitoring companies, testing each line post-migration, and disconnecting copper only after the replacement is verified and stable.
Ongoing Management & Optimization
Post-migration, RLM provides ongoing support for carrier escalations, billing issues, capacity changes, and new location deployments. We also monitor for remaining copper lines that may surface and ensure your POTS-free status is maintained as your footprint evolves.
POTS Replacement Evaluation Criteria
These are the dimensions that separate a smooth POTS migration from one that creates new problems — and the questions RLM will help you answer before you disconnect a single copper line.
Complete Line Visibility
You cannot migrate what you cannot see. Evaluate whether your current inventory accounts for every active POTS line — including lines inherited through acquisitions, lines billed to departments that no longer exist, and lines serving equipment in closets, basements, and elevator shafts that haven't been audited in years.
Use-Case-Specific Replacement
A cellular adapter that works for a fire alarm panel is not the right solution for a call center with 50 active voice lines. Evaluate whether each replacement technology is matched to the specific bandwidth, latency, reliability, and regulatory requirements of the endpoint it serves.
Life-Safety & Regulatory Compliance
Fire alarm communicators, elevator phones, and building access systems are subject to local fire codes, AHJ inspection requirements, and UL certification standards. Evaluate whether replacement solutions meet these requirements and whether your alarm monitoring company has certified the new connection method.
Cellular Coverage & Redundancy
Cellular POTS replacements depend on carrier signal at the specific device location — not just the building address. Evaluate signal strength at the actual installation point (often interior rooms, basements, or elevator shafts) and whether external antenna options or multi-carrier failover are available.
Number Porting & E911
Many POTS lines carry phone numbers that have been published, programmed into alarm panels, or registered with E911. Evaluate porting timelines, interim call forwarding strategies, and whether the replacement provider supports proper E911 address registration for each location.
Total Cost of Ownership
POTS replacement typically reduces per-line costs by 40-60%, but the savings depend on replacement technology selection, contract terms, and equipment costs. Evaluate the full TCO — hardware, monthly service, installation, monitoring fees, and the cost of maintaining any remaining copper lines during a phased migration.
The Copper Clock Is Ticking
Major carriers have been systematically raising POTS line rates, reducing repair commitments, and filing for copper retirement in markets across the country. Organizations that wait for carrier-forced disconnection lose control of their timeline, their technology choice, and their negotiating leverage.
The FCC's copper retirement rules allow carriers to discontinue POTS service with as little as 180 days notice. By the time you receive that notice, procurement lead times and installation backlogs may make a smooth transition impossible.
Common POTS Use Cases We Migrate
- Fire alarm panels & communicators
- Elevator emergency phones
- Building gate & access control systems
- Fax machines & analog modems
- Point-of-sale terminals
- Lobby & common area phones
- Burglar alarm & intrusion panels
- Conference room analog lines
"We had 340 POTS lines across 80 locations — some we didn't even know about. RLM audited everything, migrated us to cellular and SIP, and cut our monthly telecom spend by over 50%."
The benchmark comes first. Without a baseline, “savings” is just a number a vendor gave you.
