POTS line replacement for property managers and HOAs

Who this page is for

• You manage multifamily, HOA, condo or commercial buildings with elevators, gates, fire alarms or pool phones.
• Your phone bill has more lines than anyone can explain.
• A carrier notice arrived, or the line charges jumped, and the owner or board wants a plan.
• You will need vendor schedules, a budget and a short memo for approval.

The situation most property managers start from

The notice usually lands on the front desk. It names a service address, a date and a replacement offer. The building has three to ten lines on the bill, and the last person who knew what they were for left years ago.

Meanwhile the elevator company is asking about the cab phone, the alarm company wants to sell a communicator, and a board member read that copper is going away everywhere. The fastest way through is an inventory, then a sorted list.

Step 1: Inventory every line, building by building

Work from both ends: the bill and the building.

1. Pull the bill. List each phone number, the service address and the monthly charge. Ask the carrier for a full list of lines on the account, because some bills summarize lines under one main number.
2. Walk the rooms. Check the telecom room or demarc, the elevator machine room, the fire alarm panel, the gate operator, the leasing office and the pool equipment room.
3. Match number to device. Labels help. Where there are none, a low-voltage technician can trace pairs with a tone generator, and the alarm and elevator contractors can read the numbers programmed in their equipment.
4. Record the details in one sheet: building, number, device, room, vendor responsible, monthly cost, notice date.
5. Flag lines that serve nothing. These are candidates to cancel after a short test period.

A sample inventory row looks like this:

Building	Number	Device	Room	Vendor	Monthly cost	Notice date	Plan
Building A	(from bill)	Elevator 1 cab phone	Machine room	Elevator contractor	(from bill)	(from notice)	Replace
Building A	(from bill)	Fire panel line 1	Electrical room	Alarm company	(from bill)	(from notice)	Replace
Building A	(from bill)	No device found	Demarc	None	(from bill)	(from notice)	Test, then cancel

Step 2: Sort by risk and by date

Put life-safety lines at the top: elevator emergency phones, the fire alarm panel and any area of refuge or emergency call box dial-out. Then gates and pool phones, then fax and card terminals, then plain voice lines.

Within each group, the building whose notice date comes first goes first. Under the FCC’s 2026 rules, a carrier’s customer notice must go out no later than the day it files to discontinue service, and it must describe replacement options (FCC 26-19). My AT&T copper retirement guide explains how to read the notice and what the date means.

Step 3: Price the change and build the budget

Get two written quotes for each line type. For the comparison, collect the same six numbers from each:

• Monthly cost per line, including monitoring and data
• One-time hardware and installation cost
• Contract length and early termination terms
• Battery runtime
• Who installs and who tests
• What is not included (elevator contractor visit, permit fees)

AT&T’s December 2025 FCC application lists its business replacement at $99.99 per month before taxes and fees, with an AT&T-owned device (filing). Use it as one comparison point, not as the default for every line.

Put your bill and each quote into the POTS replacement cost calculator. It shows the monthly difference, the break-even month for the one-time cost and the total over the contract.

Step 4: Get owner or HOA board approval

Boards approve faster when the memo answers their questions before they ask. Keep it to one page:

• What is changing and the date on the carrier's notice
• Which systems depend on the lines (elevator, fire alarm, gate, pool)
• Two quotes side by side, with monthly, one-time and contract totals
• Lines you plan to cancel and the savings
• The vendor schedule and the target cutover date
• What happens if the board waits past the notice date

Check who can sign. A 36-month or 60-month contract may exceed what your management agreement lets you sign without the owner or board.

Step 5: Coordinate the elevator and alarm vendors

These two vendors set your schedule.

• Elevator contractor. Reprograms the cab phone’s dial-out numbers and location message, tests every car and handles any permit. If your maintenance contract includes phone monitoring, ask what changes. Washington’s elevator program notes that cars can share a line if the emergency call has priority, under the 2016 code (TC 18-04), but your inspector sets the rule for your edition.
• Fire alarm company. Recommends a communicator or tests the panel on the new line, updates the monitoring account and handles the fire marshal.
• Gate vendor. Reprograms the entry system’s directory if numbers or dialing change.

Send each vendor the same short letter: the building, the line, the cutover date and what you need from them. Book them for the same day as the line installer when you can.

Step 6: Roll out across a portfolio

For more than a handful of buildings, run it as a project:

1. Pilot the hardest building. Deep basement, oldest panel, most lines. If it works there, it works elsewhere.
2. Standardize by building type. For example: garden-style with gate and pool, mid-rise with one or two elevators, high-rise with intercom and fire service.
3. Group by notice date. Waves of 3 to 5 buildings keep contractors busy without double-booking them.
4. Use one portal. Ooma and Granite both describe portals that show every unit’s status (Ooma, Granite). Ooma also says it can bill by business entity or location, which helps when each building has its own owner.
5. Track acceptance. A building is done when every line passes testing and any inspection is signed, not when the box is installed.

Step 7: Tell residents what to expect

Most residents never notice. Tell them anyway when the change touches them:

• Gate and door entry: the date, a reminder to confirm the phone number in the directory, and who to contact if the gate does not call them.
• Elevator phones: a short note that the emergency phones are being upgraded and tested, so nobody worries when technicians are in the cab.
• Pool and amenity phones: the new number if it changes, posted at the phone.

My recommendation by portfolio size

• If you have 1 to 3 lines in one building: one POTS-in-a-box unit usually covers the elevator and one more line. Ask the alarm company to quote the fire panel separately, then compare. Details in POTS in a box explained.
• If you manage 5 to 20 buildings: pick one gateway provider for elevator, gate and pool lines across the portfolio, and let each building’s alarm company handle its panel.
• If you manage 20 or more buildings across states: get per-site pricing in writing, insist on one portal and one invoice format, and pilot before committing the whole portfolio.

Questions to ask any provider

• Can you quote every building on one agreement but bill each building separately?
• Who coordinates with my elevator and alarm contractors?
• Can I add or remove a building without a new contract?
• Who receives alerts, and can they go to each building's on-site staff?
• What happens to the contract if we sell a building?

Common mistakes property managers make

1. Cancelling a “dead” line that actually feeds the gate. Test each line before cancelling it.
2. Accepting the carrier’s offer for every line by default. It may fit voice lines and not the fire panel.
3. Signing a term longer than the management agreement. Get owner approval first.
4. Booking the line installer without the elevator contractor. You pay for two trips.
5. Forgetting the clubhouse, pool and gate. They are often on separate accounts.
6. Closing the project before the inspection. Keep copper active until the elevator and fire tests pass.
