POTS (Plain Old Telephone Service) replacement over cellular substitutes cellular-based voice adapters for legacy analog telephone lines — eliminating the copper infrastructure that carriers are actively retiring while maintaining compatibility with analog devices: fax machines, elevator phones, alarm panels, gate intercoms, and HVAC controls.
Telephone carriers are aggressively retiring copper POTS infrastructure — with FCC approval to abandon copper at the local exchange, organizations face forced migrations from legacy analog lines. Cellular-based POTS replacements (from providers including Lingo, Ooma, Verizon, AT&T, and dedicated POTS replacement vendors) provide a direct substitution path. RLM advises on POTS inventory assessment, replacement technology selection, and migration execution.
A structured advisory process — from environment assessment and carrier/vendor evaluation to deployment support and ongoing optimization.
We conduct a comprehensive POTS line inventory — identifying every analog line, its device type, business function, and migration complexity — distinguishing simple voice lines from life-safety systems requiring special handling.
We evaluate POTS replacement options — cellular POTS replacement adapters, VoIP ATA solutions, and carrier migration programs — matching technology to device type, connectivity requirements, and the regulatory compliance requirements of life-safety systems.
Elevator phones, fire alarm panels, and emergency call boxes are life-safety systems with specific reliability and compliance requirements (NFPA 72, local fire codes). We advise on compliant replacement approaches and the testing required for life-safety system approval.
We design the migration sequence — prioritizing non-critical lines first, preserving business continuity for critical systems, and managing carrier disconnect timing to prevent service gaps during the analog-to-cellular transition.
The dimensions that separate high-performing mobility deployments from costly ones — and the questions RLM helps you answer before any commitment.
Fire alarm panels, elevator emergency phones, and security systems have specific regulatory requirements for the communications path. Evaluate replacement technology compliance with NFPA 72, UL certifications, and local AHJ requirements before committing to a solution.
POTS replacements rely on cellular signal at the device location — basements, elevator shafts, and remote enclosures may have poor signal. Evaluate coverage before migration and the signal amplification options for challenging locations.
Fax transmission over cellular introduces timing and compression issues that affect reliability. Evaluate dedicated fax-over-cellular solutions or cloud fax alternatives for organizations with ongoing fax requirements.
POTS retirement timelines vary by carrier and geography. Evaluate whether your carrier has filed retirement notices for specific central offices and the urgency of migration in each location.
POTS replacement cellular plans typically cost more per line than the legacy rates organizations have carried for years. Build a full cost comparison including equipment, cellular airtime, and the one-time migration cost.
"RLM helped us rationalize our mobile fleet across four carriers and cut our monthly spend by 31%. They handled the whole transition — we didn't lose a single device."
"We needed private LTE across 12 distribution centers. RLM mapped the vendors, ran the RFP, and had us live in 90 days. Their knowledge of the carrier landscape is unmatched."
