When should you be evaluating POTS Replacement?
Rubber Duck has worked extensively with our POTS Replacement providers to understand where they have seen the most success and the biggest ROI for clients adopting the solution. Here is what the data reflects.
- The carrier is sunsetting copper service in your area and your fire alarm or elevator phone needs to keep working
- You’re paying $100+/month per legacy POTS line and want a fraction of the cost via cellular replacement
- You have dozens or hundreds of analog lines across sites that need standardized replacement
- Compliance (fire code, elevator code) requires a working analog line and you can’t get one anymore
- You’re decommissioning a legacy PBX but still need a few analog endpoints
What you actually get with POTS replacement
Copper tariffs keep climbing and carriers are retiring the lines outright. A proper replacement program covers life-safety, not just dial tone.
Line inventory and audit
Every copper line found, tested, and classified — fire panels, elevators, faxes, alarms, and gates.
Life-safety-grade hardware
Battery-backed LTE and fiber gateways engineered for fire-alarm and elevator code requirements.
Managed migration
Site surveys, install scheduling, and cutover verification handled end to end by the provider.
Cost containment
Escalating copper tariffs replaced with flat per-line pricing you can actually budget.
Compliance documentation
Test records and monitoring certificates ready for inspectors and insurance audits.
Pricing benchmark and redlines
Per-line quotes across finalists with monitoring-fee and term redlines.
