POTS replacement savings calculator.
Analog line pricing rises every year as carriers retire copper — and the increases compound. Enter your line environment, compare replacement approaches side by side, and see the savings, the payback period, and what waiting actually costs as POTS rates keep climbing.
Keep paying for copper, or replace it — side by side.
Is your area on the retirement path?
Copper retirement rolls out wire center by wire center, not state by state — so the reliable signals are the ones on your own account. Check what applies:
The official record of copper retirement is the carrier network-change disclosures filed with the FCC — but for planning purposes, rate increases and carrier notices on your own account are the signals that matter, and they usually arrive before any deadline does.
Estimates only. This tool produces estimates based on the numbers you enter. It is not a quote and not a guarantee of savings. Actual results depend on line-by-line verification, replacement solution selection, and code requirements — fire and life-safety lines must be migrated with your monitoring vendor involved and in compliance with applicable codes. Unravyl Advisors provides this tool for planning purposes.

The exercise behind the numbers: inventory, verify, migrate.
The savings this calculator estimates come from a specific sequence. Inventory first — pull every analog line off the carrier invoices; the count is almost always higher than anyone guesses. Verify each line at the site level — match each number to a physical function, because a meaningful share will have none. Then migrate what remains, deliberately: wireless analog adapters for elevators, alarms, and fire panels; VoIP adapters or digital fax where fax must survive. Fire and life-safety lines migrate with the monitoring vendor involved and code compliance confirmed — that’s the category to handle carefully, not to skip.
Why waiting costs more every year.
POTS pricing is not a negotiation problem — it’s a product-sunset problem. Carriers are retiring the copper these lines run on, and the pricing is designed to push customers off it. That’s why this calculator compounds the annual increase into the keep-POTS projection: doing nothing is not a flat cost, and every year of waiting converts directly into overpayment before the migration happens anyway.
Frequently Asked Questions
Is this a quote?
No — it's a planning estimate built from your line count and rates. Actual savings depend on line-by-line verification and the replacement solutions selected.
Where does the "no active function" percentage come from?
Experience. In multi-site environments, a third or more of the analog inventory typically serves no identifiable function — lines for equipment that was removed, locations that changed, and services nobody can explain. The slider lets you set your own assumption.
Can fire alarm and elevator lines really be replaced?
Yes — wireless analog adapters purpose-built for these applications are widely deployed. But life-safety lines carry code requirements, so they migrate with your alarm and monitoring vendors involved, never casually.
How do I find out if my area's copper is being retired?
The reliable signals are on your own account: rate increases, carrier migration notices, and copper-fed facilities. The official record is the network-change disclosures carriers file with the FCC — but in practice, the invoice tells you first. The risk check in the tool walks through the signals.
