Your POTS Replacement Cost Estimate
Carriers began retiring POTS infrastructure in 2024 — some rural areas have already lost analog service. Most carriers will complete sunset by 2026-2027. Plan your migration now to avoid service disruption and forced-migration price hikes.
Why POTS Is Being Retired
In 2022, the Federal Communications Commission issued an order allowing telecommunications carriers to discontinue analog POTS (Plain Old Telephone Service) infrastructure. Here's what's driving the sunset:
- Aging copper network: POTS relies on legacy copper infrastructure installed decades ago, which is expensive to maintain and prone to degradation.
- Carrier cost reduction: Digital alternatives (VoIP, cellular) require far less network maintenance and capital investment.
- FCC modernization policy: The FCC incentivizes digital-first telecom to support broadband adoption and network efficiency.
- Timeline: Most major carriers plan full sunset by 2026-2027, though some rural carriers have already discontinued POTS.
Not All POTS Lines Can Use the Same Replacement
Compliance matters. Elevator codes and alarm system standards require specific technology solutions — you cannot simply swap all analog lines for one replacement method.
- Elevator emergency lines: Building codes (ASME A17.1) mandate UL-listed cellular communicators. Consumer cell service or basic VoIP adapters will not pass inspection.
- Fire and burglar alarm systems: Monitored alarm systems must use UL-approved IP or cellular communicators with certified connection protocols. Many monitoring centers do not accept standard VoIP.
- Voice and POS lines: More flexible — can use VoIP/SIP adapters, UCaaS platforms, or cellular backup depending on reliability needs and broadband availability.
- Fax and access control: Require compatible gateway devices; not all broadband-based solutions support fax protocols equally.
The difference matters for compliance, warranty, and certification. A misconfigured elevator communicator can result in code violations and failed inspections. ITG has expertise in certifying each replacement solution to your local building and fire codes.
What Happens If You Don't Replace Them
Ignoring POTS sunset deadlines creates risk and cost exposure:
- Service discontinuation: Carriers can and will discontinue service with as little as 180 days notice. If you haven't planned a replacement, you'll face emergency migration at worst possible time.
- Emergency migration costs: Forced, last-minute replacements cost 2–3x more than planned deployments. Expect service disruption and expedited-fee premiums.
- Price increases on remaining POTS: As carriers sunset the network, prices for remaining copper lines spike. The cost to keep POTS will exceed replacement cost long before sunset.
- Reliability degradation: Aging copper network quality declines as carriers reduce maintenance investment. You'll experience more dropped calls, static, and fax failures.
- Compliance violations: If your elevator or alarm system loses service due to carrier sunset, you're out of compliance with building/fire codes until replacement is complete.
