POTS Replacement
Copper phone lines are going away — and getting expensive. InstallPros replaces old POTS lines with a modern cellular or internet gateway, so your phones, alarms, elevator lines, and fax machines keep working without the aging copper plant. We mount the gateway, wire your existing lines, port the numbers, and test every line before we leave. No vendor lock-in, no surprise fees.
When POTS replacement makes sense
- •Your carrier has raised copper-line rates or sent a retirement / sunset notice.
- •You still rely on analog lines for alarms, elevator phones, fire panels, or fax.
- •You want to keep existing phones and jacks working without rewiring the building.
- •You need life-safety lines with battery backup that outlasts a power outage.
- •You manage multiple sites and want one consistent replacement rollout.
How it works
- 1
Virtual site survey
We review how many lines you have, what devices are on them (phones, alarms, elevators, fax), and where your demarc or equipment room is. Photos are usually enough.
- 2
Fixed written quote
You get a clear quote covering the gateway mount, line wiring, configuration, and testing — including the number-porting timeline. No surprise fees after you approve.
- 3
Gateway install
Our technicians mount the gateway at your demarc or equipment room and wire each existing analog line into it.
- 4
Number porting & configuration
We coordinate porting with your provider, configure failover and battery backup, and verify dial tone on every line.
- 5
Line testing & handoff
We test every line — phones, alarms, elevators, fax — and hand off a documented line map. The install is a one-time truck roll; monthly service is billed separately by your provider.
The install is a truck roll — a one-time professional visit for the gateway mount and line cutover. Your monthly cellular or voice service is a separate subscription from the provider of your choice.
What we handle on site
- •Gateway mount — clean rack or wall mount at your demarc or equipment room.
- •Line wiring — connect each existing analog line so devices keep working on the same jacks.
- •Failover & battery backup — configured so life-safety lines stay live during outages.
- •Number porting — coordinated with your provider so numbers move without gaps.
- •Full line testing — phones, alarms, elevators, and fax verified before handoff, with a documented line map.

What is POTS replacement?+
POTS replacement swaps old copper phone lines (Plain Old Telephone Service) for a modern cellular or internet-based alternative. A small gateway device connects your existing analog phones, fax machines, alarms, or elevator lines to a cellular or broadband network — so the service keeps working after carriers retire the copper plant.
Why do copper phone lines need to be replaced?+
Carriers are retiring copper networks, and many businesses have seen prices rise sharply or received sunset notices. Lines that stay on aging copper become expensive and unreliable. Replacing them with a cellular or internet gateway keeps the same jacks and devices working without depending on the old plant.
Will my alarm, elevator, or fax line still work?+
Yes — that is the main reason businesses do POTS replacement. We install a gateway that presents a standard dial tone to your existing equipment, so alarms, elevator phones, fire panels, and fax machines keep working on the new connection. We test each line after cutover before we leave.
Does the replacement work during a power outage?+
Gateways include battery backup, so life-safety lines like elevator phones and alarms stay live during an outage — often longer than the old copper line would. During the survey we confirm which lines are life-safety and make sure they get backup power.
Do you provide the monthly service or just the install?+
InstallPros is the installation and turn-up partner. We mount the gateway, wire your existing lines into it, port or verify numbers with your provider, and test every line. The monthly cellular or voice service is billed by the service provider you choose. We do not lock you to a specific brand.
What does the on-site install cover?+
We mount the gateway at your demarc or equipment room, connect each existing analog line, configure failover and battery backup, coordinate number porting with your provider, and test every line — phones, alarms, elevators, fax — before handoff. You get a documented line map.
How long does installation take?+
A single-site POTS replacement is usually a same-day or next-day visit once numbers are ported and the gateway is on hand. The porting window is the main variable — often one to three weeks depending on the releasing carrier — which we flag in the quote so you can plan around it.
How do quotes work?+
Every job is scoped first. We run a virtual site survey (how many lines, what devices are on them, where the demarc is), then send a fixed written quote covering the gateway mount, wiring, configuration, and line testing. No surprise fees after you approve. Monthly service is separate.
