Managed POTS replacement
Copper is retiring.
Your elevator phone is not.
LineBridge replaces the analog lines your building legally depends on with a managed POTS box on 5G/LTE or fiber — battery backed, monitored 24/7, and priced flat at about $9 per line.

How it works
One box between your analog equipment and the modern network
Your devices keep speaking analog. The box speaks 5G, LTE, or fiber on the other side and terminates the call on the public telephone network under the same phone number.
The short answer
POTS replacement keeps analog lines working after copper is retired. A managed device presents standard dial tone to your existing elevator phone, fire alarm DACT, or fax machine and carries the call over 5G/LTE or fiber instead of a copper pair — with battery backup, continuous supervision, and your original phone numbers intact.
Real analog dial tone
Loop current, ring voltage, and timing that alarm dialers and fax machines actually accept — not a consumer ATA hanging off the office network.
Battery-backed by design
Internal LFP battery keeps every line alive for up to 24 hours of standby after a power loss, which is what elevator and fire code expects from an emergency path.
Multi-carrier failover
Carrier-agnostic SIMs move between networks automatically, with fiber or broadband available as a primary path and cellular as the backup.
Every line supervised
Loss of dial tone, loss of signal, and battery events raise an alert to your team and ours. Copper failed silently; this does not.
Nothing else changes
The elevator phone, the fire panel, the DACT programming, and the phone numbers all stay exactly as they are. No contractor scope creep.
Published, flat pricing
$40 per month for up to 2 lines, $70 for 8, $90 with 5G/LTE. Same rates in every state — no tariff, no annual increase.
The process
Audit first. Replace only what has to be replaced.
Most estates are paying for lines nobody can identify. We find those before we quote anything, because the cheapest line is the one you disconnect.
- 01
Line audit
We read your actual invoices and identify every analog line, what it serves, and what it costs. Lines feeding equipment that no longer exists get disconnected, not replaced.
- 02
Design and coverage check
We validate cellular coverage per address, choose cellular or fiber transport per site, and size the number of boxes and antennas required.
- 03
Port and install
Boxes ship preconfigured and labeled. Numbers port on a scheduled date, lines are connected, and every alarm and elevator line is tested end to end with the monitoring center.
- 04
Monitor and document
Copper is released only after documented success. From there every line is supervised 24/7 and you get the inventory, test logs, and device records for inspections.
Pricing
About $9 per line, published and flat
No tariffs, no annual escalators, no per-state variation. What you see is what every site pays.
Up to 2 lines
$40/mo
Compact cellular device, all-in: connectivity, battery backup, monitoring, and replacement.
Up to 8 lines
$70/mo
Eight-line device on your fiber or broadband circuit, everything else included.
8 lines with 5G/LTE
$90/mo
Outdoor-rated device with multi-carrier cellular transport and automatic failover.
Plus a one-time $149 install per site, waived on 36-month terms above ten lines.
Industries
The lines that cannot simply be switched off
Every industry keeps a different short list of analog lines. These are the ones we replace most often.
Elevator phone lines
Elevator phone line replacement swaps the copper POTS line feeding an elevator emergency phone for a managed device that carries the same analog signal over 5G/LTE or fiber. The elevator phone, dialer, and cab wiring stay exactly as installed, and the line keeps working through a commercial power outage on internal battery.
Fire alarm communicators
Fire alarm POTS replacement moves the copper lines feeding a DACT (digital alarm communicator transmitter) onto managed cellular or fiber transport. The panel keeps dialing the central station exactly as programmed, while the transport path is supervised and alerted on so a failed line is caught in minutes rather than at the next test.
Healthcare
Healthcare POTS replacement consolidates the analog lines a hospital or clinic still depends on — elevator phones, fire alarm DACTs, nurse call auto-dialers, blood bank and freezer alarms, and fax — onto managed cellular or fiber transport with 24/7 supervision, without touching the clinical devices themselves.
Retail and multi-site
Multi-site POTS replacement standardizes the analog lines in every location — alarm panels, elevator phones, fire lines, and back-office fax — onto identical managed boxes with cellular or fiber transport, one consolidated invoice, and one portal showing the state of every line in the estate.
Banking and ATM
Banking POTS replacement moves branch alarm lines, vault and duress circuits, elevator phones, and ATM dial-backup onto managed cellular or fiber transport. Signaling to the central station is preserved, paths are supervised continuously, and every cutover produces documentation suitable for audit and examination files.
Education
Education POTS replacement moves campus emergency phones, blue-light call boxes, elevator lines, fire alarm communicators, and portable-classroom lines onto managed cellular or fiber transport, keeping every safety line working and monitored while removing per-line copper charges from the district budget.
Hospitality
Hospitality POTS replacement moves the analog lines a hotel is required to keep — elevator phones, fire alarm communicators, pool and spa emergency phones, and house fax — onto managed cellular or fiber transport with battery backup and continuous monitoring, with no work inside guest rooms.
What customers say
Projects that started with a bill nobody could explain
“We had 46 analog lines across nine buildings and a carrier notice giving us 90 days. Every elevator and fire line was cut over without a single inspection issue.”
Regional healthcare system
“Our copper bill was north of $4,300 a month for lines nobody could explain. The line audit alone paid for the project twice over.”
Multi-site retail group
“The part that sold us was the monitoring. We get an alert before the elevator company does, not three weeks after a line quietly died.”
