How do I tell which number my Mircom panel currently dials for my unit?

Have someone dial your unit from the lobby and see which phone rings. The building office or the access-control vendor that services the panel holds the directory, so if the wrong phone rings, they are the ones who update the entry.

My unit uses an in-suite handset instead of ringing a phone. Can that work?

Only if the panel can be programmed to dial an outside phone number for your unit. Many buildings run a mix, some suites on handsets and some on phone numbers, so ask whether your unit can be switched to a dial-out entry. If the system is exclusively hardwired handsets with no dial-out, a phone-based approach cannot attach to it.

Does this affect the fire or accessibility functions of the panel?

No. Changing the number a unit dials is a directory edit and does not modify the panel's hardware, wiring, or life-safety functions. The panel operates exactly as before for every other unit.

How to Answer a Mircom Intercom From Your Phone (No New Hardware)

By Ty · 2026-07-06

Mircom telephone-entry systems, including the Enterphone line, run building entrances across North America. When a visitor selects your unit, the panel dials the number on file and a keypress unlocks the door. Simple, except the number on file is usually somebody’s personal cell, so entry for your whole household depends on one phone being answered, charged, and not in a meeting.

Because the panel is placing an ordinary phone call, you do not need Mircom hardware, an installer, or the board’s blessing to modernize your unit’s entry. You need a better number for the directory.

How to fix it

Option	Pros	Cons
Keep a personal cell on the directory	Free, no changes	Single point of failure for every arrival
Google Voice number	Free, rings multiple phones at once	Still a live call to answer, no passcodes, no automation
In-suite handset only	No phone dependency inside the suite	Someone must be physically home to let anyone in
Lowkey	Auto buzz-in, passcodes on the panel keypad, scheduled access, entry history, multiple phones	Quick one-time setup with your building

The first two options move the ringing around; they do not remove the need for a human to answer. If the point is that deliveries, guests, and recurring services get in whether or not you pick up, you want the call answered by software. Two questions in the free compatibility checker will confirm your setup dials out.

Where Lowkey helps

Lowkey gives your unit a dedicated virtual number for the Mircom directory. Calls from the panel ring the Lowkey app on every phone in your household, and the app can answer for you: automatic buzz-in when you are expecting someone, 4-digit passcodes for guests and cleaners, time-limited access that expires on its own, and a log of every entry. It works with any buzzer that dials out to a phone number, which covers Mircom and Enterphone panels and most other apartment and condo systems, with nothing installed and nothing rewired.
