RETIRE THE COPPER.
KEEP EVERYTHING RINGING.
A fully managed POTS replacement on the Verizon network. Fire alarm, elevator, fax, modem and voice lines moved off copper, installed nationwide and watched 24×7. Billed on your carrier bill.
Line, device and estimated Verizon data, before taxes and fees, when you own the hardware and fill all four ports. One line alone is $67.50.
Price your own lines. In under a minute.
Start with a quick count, or lay out one site exactly and multiply it. Either way you see the same three numbers: what it costs per line, per month, and up front.
How many locations, and how many copper lines at each one. Count 2 lines for every fire alarm panel.
Lay out one site (a fire alarm panel and an elevator, say), then tell us how many sites look like that. Each fire alarm panel takes 2 lines.
Indicative pricing. Excludes applicable taxes and fees. Your Masters rep confirms the final quote.
One device. One data plan. Up to four lines.
Every AirDial carries up to four lines, and the device and its Verizon data plan are shared across all of them. On a rented device that takes the average from $67.50 a line down to $39.38.
Recurring monthly, per site. Includes the $15/mo Verizon data plan: one activation per AirDial, shared by every line on that unit. $30 per line/month applies to both options. Rent adds a one-time $125 per device. Own is $395 per device up front, optional $300 pro install, no monthly device fee.
Rent the hardware, or own it.
Same AirDial either way. Same $30 per line. The only question is where the device lands on your books, and either one shows up on your carrier bill.
$125 one-time activation, configuration and deployment
+ $300 optional professional install, per location
Verizon data plan not included. Each AirDial needs its own Verizon FWA activation, about $15/mo, on your carrier bill.
Purpose-built to replace a copper line.
Not a repurposed router with an adapter bolted on. Four analog ports, its own battery, two network paths and a portal that tells you it is up.

Battery backup built in
A replaceable 85.4 Wh (7.8 Ah) Li-ion pack provides backup power during an outage. Expected runtime depends on line load, signal conditions, battery condition and the site; an optional external battery extends it.
Designed for life safety
Designed with the applicable guidelines of:
Managed from one portal
Live service status, wireless signal and battery across every device and location. Alerts by SMS and email when the portal detects an outage or low battery, with role-based access for your team.
From line review to live, and watched ever after.
Nine steps, one team. We inventory what you have, survey with our own tools, quote from real evidence, manage the ports, and keep watch once it is live.
POTS Onboarding Tool
Turns raw customer records (PDF bills, spreadsheets or manual entry) into a reviewed line inventory in one workflow. It identifies the line type behind every number and flags unknown, ambiguous and duplicate lines for a human to confirm.
Masters Site Survey
A guided, mobile-first survey app. The virtual survey is free. Run it with your team over a call, or send a tech on site. Either way it captures signal readings, line inventory, photos and install constraints, then produces a scoped bill of materials.
Watched 24×7
Service status, wireless signal and battery on every unit. SMS and email when the portal detects a line-state change or low battery, and 24×7 escalation to the same engineers who scoped your sites.
Mounted, aimed, and dialed before we leave.
Nationwide install teams mount the units, power them, aim the antenna and test against the panel. Every line is dialed and confirmed on site, not marked complete from a truck.
Send us a bill. We’ll send back an inventory.
Your calculator numbers travel with the form. We come back with a reviewed line inventory and a preliminary quote, usually inside one business day.

The honest answers.
Will my fire marshal accept it?
The AirDial is built to the applicable guidelines of UL, NFPA 72, the California Fire Marshal and ASME A17.1B. Acceptance is still granted jurisdiction by jurisdiction. Check with your local fire, elevator and alarm authorities before you transition, and we will help you get the answer in writing.
What happens in a power outage?
Each unit carries its own replaceable Li-ion battery, sized to keep its lines working through a typical outage, and an external battery extends that further. The portal is designed to alert you when a unit switches to battery. Runtime depends on the site, and we size it with you at survey.
Do we keep our phone numbers?
In almost every case, yes. We manage the port for each line and confirm portability during the line review, before anything is scheduled. Panels, dialers and elevator phones keep dialing the same numbers to the same monitoring centers.
What if there is no signal in the basement?
The survey answers that before anyone is dispatched. Where signal is weak we specify an external 4G antenna at survey, and the unit can also run over building Ethernet as a second path.
How am I billed?
Available on your carrier bill: lines, devices and the Verizon data plan land in one place instead of a stack of copper invoices. Prices exclude applicable taxes and fees.
We have 80 locations. Is this the price?
The calculator is a planning estimate up to 50 locations. At 50 or more, reach out. Large estates are priced custom, and the survey and rollout are staged rather than booked all at once.
