Retire the Copper. Keep the Phone Line. Dunwoody POTS Replacement.
Carriers are retiring analog copper. Justin Hall Consulting installs cellular-managed POTS replacement devices that keep elevator phones, fire alarms, gate intercoms, and fax lines working in Dunwoody buildings. No copper, no surprise bills, and the same RJ-11 jack the legacy equipment plugs into.

Copper is going away. The lines you depend on don't.
AT&T and the other carriers have been deregulating analog copper phone service for years. The lines that used to cost Dunwoody property managers $30/month now run $100 to $300. When a line fails, technician dispatch is weeks out. The lines that elevator phones, fire alarms, gate intercoms, and fax machines actually need are not going to be repaired the way they used to be.
We migrate Dunwoody buildings off copper with cellular-managed POTS replacement devices. Each device gives the legacy equipment the same RJ-11 jack it was wired for, carries the call over LTE (with Wi-Fi failover on dual-pathway models), and reports its own health to a dashboard you can audit. We pull the old copper bill, audit every line you have, install the new devices, and document everything.
Six legacy lines we retire from Dunwoody buildings
Each one has its own compliance requirement. We migrate them all with one site visit.
Elevator phones
ASME A17.1 requires a two-way emergency phone in every elevator car that can reach help 24/7. Cellular POTS devices keep that compliance without the copper bill.
Elevator phonesFire alarm lines
NFPA 72 fire alarm circuits used to depend on dedicated copper to reach the monitoring station. Dual-pathway cellular devices meet the code with two independent paths.
POTS hubGate & door entry
Telephone-entry call boxes at parking gates and apartment lobbies still call out over a phone line. We swap the copper for cellular without touching the box itself.
POTS hubFax lines
HIPAA, banking, legal, and healthcare offices still need an inbound fax number. We keep your fax number and the analog signaling, just on cellular underneath.
POTS hubBurglar & facility alarms
Central-station alarm panels that dial out for monitoring keep that exact behavior, just over LTE. We pre-stage the unit, swap the line, and verify with the monitoring center.
POTS hubPool, generator & courtesy phones
Phones at the pool, the loading dock, the generator, the lobby. Any analog phone in a non-staffed location with a 911 obligation gets the same cellular treatment.
POTS hubCertified for the codes Dunwoody buildings have to meet
Independently certified compliance with NFPA 72, ASME A17.1, UL 1981/2050, HIPAA, FCC, PCI DSS, UN 38.3, and state fire marshal requirements.
The reasons multi-line operators stay
We audit before we quote
We pull your copper carrier statement, walk the building, and produce a line-by-line audit. You get a real number of how many lines you have and what they actually cost, before any migration starts.
Every device is documented
Label, location, dialed number, dashboard ID, and the legacy line it replaced. When something needs attention two years out, the IT and property-management teams have one source of truth.
Multi-site rollouts are the work
Property managers with portfolios across GA get the same install standard, the same labeling, and the same monthly bill format at every building, not five different cellular vendors invoicing separately.
We coordinate the disconnect
Once the cellular device is live and tested with the monitoring center, we file the disconnect with the copper carrier on your behalf. The bill stops the next billing cycle.
Got a copper bill that keeps climbing in Dunwoody?
Send us the address. We will walk the building, audit the lines, and produce a real number. The audit is free and there is no obligation.
Get a Free POTS AuditFour steps, no surprises
Site audit
We walk the building, identify every analog line, and document the legacy device each one feeds. A line you forgot you were paying for is the typical first surprise.
Migration plan
We map each legacy line to the right cellular device model (standard or dual-pathway), confirm cellular coverage at each location, and put together the migration schedule.
Install & verify
Devices pre-staged in our shop. On site, we install the unit, plug the legacy device into the same RJ-11 jack, and run a verification call with the monitoring station before we leave.
Disconnect & document
We file the copper disconnect with the carrier on your behalf and deliver the as-built documentation. Your IT and property-management teams have one source of truth.
Questions Dunwoody property managers ask us
Will my elevator phone still pass inspection on cellular?+
Yes. ASME A17.1 requires the elevator phone to reach help and identify the car location 24/7. Dual-pathway cellular POTS devices are explicitly listed for elevator compliance. An inspector knows them and signs off without issue. We hand you the device certification documents at install.
How long does a Dunwoody migration take?+
For a single building with one or two lines, a few hours on site. For a portfolio with dozens of lines across multiple addresses, the install schedule is typically two to six weeks, sequenced around your operation. The site audit and migration plan come first, before any equipment is ordered.
What happens to my phone number?+
We keep it. The cellular device gets ported the existing copper-line number, so anything that calls or texts the elevator, the alarm panel, or the fax machine keeps the same identity. No reprinting building signage, no notifying tenants of new numbers.
What does it cost vs the copper bill?+
Cellular POTS is typically $30 to $60 a month per line. Copper lines for elevator/alarm service have crept to $100 to $300 a month per line in Dunwoody. The audit gives you a real number for your building so the decision is based on your actual lines, not someone else's.
Do you handle multi-site portfolios?+
Yes, that is most of our work. We install the same device model, the same labeling, and the same documentation at every address, with one point of contact for the whole portfolio. The dashboards roll up so the IT or property-management team can see every device in one view.
What if cellular coverage at the building is weak?+
That is what the audit catches. We test cellular signal at the exact panel/jack location during the walk. If one carrier is weak, the device supports a different one. If LTE is marginal, we use a dual-pathway model that adds Wi-Fi as the second path.

POTS Replacement in the Perimeter Office Parks
Dunwoody is the center of the Perimeter submarket, and the office towers along Hammond Drive, Ashford Dunwoody Road, and Mount Vernon Road were built between the mid-1980s and the early 2000s. These class-A and class-B buildings were designed with dedicated copper infrastructure for fire panels, elevator monitoring, and access-control dialers. That infrastructure served the buildings well for 20 to 30 years. What the original designers did not plan for was a carrier decision to retire the copper network that fed it.
AT&T has been actively retiring copper circuits in the Perimeter submarket as part of its national copper-to-IP transition. Buildings in Dunwoody's office-park corridors have received copper-retirement notices in waves since 2022, with varying lead times. Some notices have given building operators 90 days. Others have given 30. A class-A office tower with six elevators and a multi-zone fire panel can have a dozen or more POTS circuits to replace, each tied to a different compliance requirement and a different contractor. Replacing them one at a time as each one fails is more expensive than doing a coordinated assessment and replacement project.
For a Perimeter-submarket building in Dunwoody, the right replacement approach is usually a building-wide POTS audit: identify every copper circuit by function, determine the replacement path for each (IP communicator, cellular, or analog telephone adapter depending on the device), and complete all replacements in a single coordinated project. That approach is faster, cleaner, and cheaper than the reactive route. We have completed coordinated POTS replacement projects at multi-floor office buildings in the Perimeter Center East and Perimeter Center West developments. A site audit is the first step and costs nothing.
