If you are still paying for POTS lines, you have probably seen the bill climb hard the last few years. That is not an accident. The FCC ended price protections on legacy copper lines, and the major carriers are actively retiring the network. Lines that used to be $40 a month routinely run $100, $200, even $300 now. Some businesses have been forced off entirely.
Here is the honest comparison between what you have on copper and what hosted VoIP looks like in 2026, from an operator in Ocoee, FL who handles both sides of the migration. We are the platform, not a middleman, so when something needs attention it goes to engineers, not a queue.
What POTS actually is, and why it is going away
POTS (Plain Old Telephone Service) is the analog copper line system that has been in the ground for over a century. It works with an on-premise PBX, an analog modem, an elevator phone, a fax machine, an alarm panel. It is reliable in a power outage because the line carries its own voltage.
The catch: the copper plant is old, expensive to maintain, and the carriers are not investing in it. The FCC's Order 19-72A1 removed the requirement for carriers to keep selling it at regulated prices. Result: prices climbed, availability dropped, and "sorry, no longer available at this address" letters have been hitting business mailboxes for the last three years.
What "the carriers are retiring it" looks like in practice
You get a letter saying your POTS rate is changing to a higher tariff. A year later, the rate changes again. Then you call to add a line and you are told the central office in your area no longer provisions new copper. Then a tech comes out for a service call and tells you the cable in the street has water in it and the fix is a wireless replacement. None of that is hypothetical. It is the standard playbook now.
The FCC POTS transition, in plain English
Until 2019, ILEC carriers (the original local telcos) had to offer POTS at regulated prices to most business customers. After Order 19-72A1, that requirement went away. The carriers can now price POTS at whatever the tariff allows, and they have used that freedom to raise prices fast. The strategic goal is straightforward: make copper unattractive enough that customers move themselves to fiber or cellular, so the copper plant can be decommissioned without a fight. It is working.
What hosted VoIP is
Hosted VoIP moves the phone system off copper and into the cloud. Your phones (desk, mobile app, softphone) talk over the internet to a PBX we run in our data centers. Calls hit the public phone network through our SIP trunks. No box in your closet, no copper lines to lease.
Our phone service is $15 or $32 per user per month. Pro Mobile runs $42 to $62 if you want to replace the cell phone allowance at the same time. Full numbers are on the pricing page.
How a single line on copper becomes a user on VoIP
A POTS line is one thing: a wire to a single phone. A VoIP user is an extension that can ring a desk phone, a mobile app, a softphone, and a remote office at the same time, with voicemail, call recording, and CRM integration attached. The price-per-line comparison undersells the feature difference. You are not buying the same product for less. You are buying a much better product, also for less.
Cost comparison, real numbers
A 10-line POTS setup at today's prices:
- 10 POTS lines at $150 average = $1,500/month
- Long-distance and feature charges = $100 to $300/month
- PBX maintenance contract = $100 to $200/month
- Total: $1,700 to $2,000 per month
The same business on hosted VoIP:
- 10 users at $32/month = $320/month
- Bundled US calling, all features included
- No maintenance contract
- Total: about $320 per month
The savings are not subtle. They are also not the whole story; we still have to handle the analog edge cases.
What the savings buy you
If you redirect even half the savings, you can add Pro Mobile for your field staff, swap a few desk phones for new Yealink T46U units ($269) or T54W ($289), put an AI Receptionist on the after-hours line, and still come out hundreds of dollars per month ahead. The legacy bill was paying for nothing; the hosted bill pays for the features that actually run the business.
What the five-year picture looks like
$1,700 a month on legacy is $102,000 over five years. $320 a month on hosted is $19,200 over five years. Even adding $30,000 in incremental features (Pro Mobile, vFAX, AI Receptionist, new hardware), you come in under $50,000 against the legacy $102,000. The savings are the budget for everything else you needed but could not justify on the old system.
The analog edge cases (and the answers)
POTS lines often serve things that are not phones: faxes, alarm panels, elevators, gate intercoms, modems. Each one has a hosted answer:
- Faxes: vFAX at $25, $35, $49, or custom per month. Sends and receives faxes from a portal or email. HIPAA-eligible at the $49 tier.
- Alarm panels: most modern panels support cellular or IP communicators that replace the POTS line. Your alarm company can swap the module.
- Elevators: dedicated cellular elevator phone modules are the standard answer now. Code-compliant.
- Fax machines: ATA (analog telephone adapter) lets the existing fax machine work over VoIP. Not perfect, vFAX is better.
- Gate intercoms: cellular intercoms or IP intercoms. Newer systems also support SIP directly.
- Credit-card terminals: almost all have IP or cellular options now. Check with the processor; the POTS option is usually the slowest and most expensive.
- Modems for legacy systems: rare now, but if you have a backup modem somewhere, cellular modem is the replacement.
The fax conversation specifically
Healthcare, legal, and insurance still run real fax volume. vFAX handles it cleanly over IP, with a portal for sending and receiving, email-to-fax for users, and a HIPAA BAA at the $49 tier. We see practices kill three POTS lines and a maintenance contract by moving fax to vFAX alone. See the healthcare phone system and dental phone system pages for the full setup.
The alarm panel conversation specifically
Old alarm panels relied on POTS for communication to the monitoring station. Modern panels use cellular or IP, and the cellular communicator is the most common drop-in replacement. The alarm company comes out, swaps the module, updates the account, and the POTS line for the alarm goes away. Same for fire alarm panels (subject to AHJ approval in some jurisdictions). The fix is well-known; the only question is who initiates it.
Reliability, the honest version
POTS used to win on power outages. With copper actively being retired and prices spiraling, that argument is shrinking. Hosted VoIP reliability comes from:
- A business-grade internet circuit with QoS for voice.
- Pro Mobile on cellular as the failover when the office circuit drops.
- Geo-redundant call routing on our platform.
For HIPAA workloads in healthcare, we offer a $49/month HIPAA add-on with the BAA in place. See healthcare phone systems.
What we do not pretend
If your only internet option is a 3 Mbps DSL line that drops twice a week, hosted VoIP is not going to be magically reliable. We will tell you that on the first call. The fix is either a better circuit (cable, fiber, or fixed wireless as a second path) or sticking with the legacy system until a better option is available at your address. We would rather lose the sale than sell a system that will frustrate you.
What a dual-circuit setup looks like
The strongest configuration is a primary business circuit (fiber or cable) for the office, plus a cellular failover router that takes over if the primary drops. Pro Mobile on the team's phones gives a third path. Three-path redundancy is overkill for most businesses, but the cost is small and the result is uptime that exceeds copper.
What porting and switching looks like
Number porting is $15 per number. We file the paperwork with the losing carrier, set up the new system in parallel, and cut over once it is tested. Typical timeline is 2 to 3 weeks. E911 addresses get registered (misdial fees are $150 if the address on file is wrong, so we double-check). Old PBX and copper get disconnected last.
The cutover playbook
- We size your concurrent call volume and pick the right plan.
- You order any phones you want from the hardware page or bring your own.
- We provision extensions, set up the auto-attendant, build the call flow.
- You test everything in parallel: inbound, outbound, voicemail, E911.
- We file the port requests with the losing carrier.
- On cutover day, numbers move and the new system goes live.
- Old POTS lines get disconnected last, once we confirm everything works.
What can go wrong and how we handle it
- Port reject from the losing carrier. Usually a name or address mismatch. We fix and resubmit.
- Port date slips. The losing carrier controls the calendar within a window. We hold cutover until the new and old are both ready.
- Hidden analog line. We do a walkthrough before cutover. Sometimes a line shows up that nobody knew existed. We plan a replacement before disconnecting.
- QoS not configured on the LAN. If the router was set up by the office manager's nephew, we send a config or recommend a network partner.
Common mistakes when leaving POTS
- Cancelling POTS before porting. If you disconnect first, the number is gone. Always port, then disconnect.
- Missing an analog endpoint. Walk the building. Find every line. Fax, alarm, elevator, gate, back-room credit card terminal. Each one needs a plan before cutover.
- Underestimating bandwidth. 10 concurrent calls plus video meetings plus cloud backups is more than 25 Mbps. Size for peak.
- Letting E911 default. Every endpoint, especially mobile and remote-work softphones, needs the current address on file. The $150 misdial fee is avoidable.
- Skipping the test phase. A side-by-side test in parallel for a week catches problems that a one-day cutover hides.
- Trusting a fly-by-night provider. A reseller with a phone number and a website cannot actually fix carrier-level problems when they happen.
- Trying to save by ATAing the fax machine. ATAs work for occasional faxes. For real volume, vFAX is more reliable and cheaper to maintain.
What to ask before you sign
- Are you the operator or a reseller? Who actually fixes the platform when it breaks?
- What is included at the headline price? Is voicemail-to-email free? Is transcription extra? Is SMS extra?
- What is your plan for my fax, alarm, elevator, and gate lines?
- What does the porting timeline look like for my number count?
- What happens during an office internet outage?
- If I am HIPAA-regulated, do you sign a BAA, and on which products?
- How long does it take to add a user or change a greeting after install?
Where to start
If your POTS bill has crossed $500 a month, the math is already in favor of switching. Tell us what you have and we will price it. Get started, see pricing, compare us to Nextiva, RingCentral, or Ooma, or talk to us in Ocoee. The conversation is short, and if hosted VoIP is the wrong answer for your specific situation, we will say so.
What POTS retirement looks like by industry
The pace and pain of the POTS transition differ by industry. Here is what we are seeing in 2026:
Healthcare and dental practices
Most practices have 4 to 12 POTS lines (front desk, fax, after-hours, alarm). The fax lines are the hardest part because of HIPAA. vFAX at $49 includes a BAA and handles the volume cleanly. Front-desk lines move to a hosted PBX with screen-pops to the practice management system. After-hours can move to AI Receptionist with the HIPAA add. Whole transition is usually 4 to 6 weeks for a 10-provider practice. See healthcare phone system and dental phone system.
Legal firms
Smaller line counts, but high call value. The IVR is usually too long and the after-hours plan is voicemail. Moving to hosted with proper queue routing, recording for compliance, and integration to the case-management system is usually a 2 to 3 week project. Fax volume varies; some firms still receive a hundred faxes a week and others have already migrated to e-filing.
Property management
Maintenance lines, leasing lines, owner statement faxes, and a handful of office lines. The biggest gain is integration into AppFolio, Buildium, or Rent Manager so the call shows the unit and tenant before you answer. AI Receptionist on the maintenance line for after-hours triage stops the bleed of 2 AM "my toilet is running" calls going to voicemail.
Field service trades
The phone is the entire dispatch operation. POTS lines feed a desk PBX that nobody can change. Moving to hosted with Pro Mobile for the techs and a ServiceTitan or Housecall Pro integration is usually the largest single-day productivity gain we see. Calls get logged, jobs get scheduled, the office knows where every tech is. See field service.
Real estate offices
Mostly individual agents on personal cells with a few office POTS lines for the broker. The transition usually moves the agents to Pro Mobile (work number on their phone, calls logged in Follow Up Boss) and the office lines to hosted. The personal-cell-as-work-phone problem solves itself in the process.
One more cost worth naming
The biggest hidden cost of staying on POTS is the deal you do not close because the customer could not reach you, did not leave a voicemail, or got tired of the IVR loop. Hosted VoIP with proper routing, queues, and after-hours coverage captures the calls that used to die. That number is hard to measure precisely, but on the businesses that switched and then looked, it was always more than the line-cost savings. The phone is a revenue tool, not a utility. The POTS bill made it look like a utility. The hosted bill makes the revenue side visible.
