Your building says you need a landline. What to ask next.
Ask your building one question: does the entry system ring through the apartment phone lines, or does the lobby panel dial out on its own phone line? If the panel dials out, it calls whatever number is stored for your unit, so a mobile number works in the same field. Only a system wired through the suite phone lines genuinely needs a line in your unit.

You asked how to get the buzzer working and were told to order a home phone. It might be true. Often it is not, and the person telling you may believe it either way.
The two kinds of system, in one manufacturer’s words
Mircom, a Canadian maker of lobby panels, sells its TX3 system in both kinds, and its user guide explains the difference plainly.
- Dial-out (Mircom calls it ADC). The panel is an auto-dialer connected to a public telephone line. When a visitor enters your code, it dials your home or cell number, and you press 9 (or the building’s chosen digit) to open the door.
- Wired through the suite lines (Mircom calls it NSL). The panel has no phone line of its own. Equipment in the building’s telephone room intercepts the residents’ phone lines coming into the building and rings the apartment directly.
Other manufacturers use different names, but the question is the same: does the panel place an ordinary phone call, or does it ring the wiring in your suite? What the panel is doing in each case.
Why it gets said when it is not true
For a long time, the number stored for each unit was usually a home phone, because that is what most households had. Staff turn over, the reason gets lost, and the habit survives as a rule. Nobody is lying to you; the panel has simply never been asked to hold anything else.
The question to ask, word for word
Send it by email rather than asking at the desk. It is a specific question with a specific answer, and it keeps the conversation off opinions about mobile phones.
| If they say | Then | Your move |
|---|---|---|
| The panel dials out on its own line | No line needed in your unit | Give them a number to store and ask them to confirm |
| It rings through the apartment phone lines | A line genuinely is required | Ask whether the building has plans to change the system |
| They do not know | Answerable | Ask for the panel make and model, or check it yourself |
You can often answer it yourself in a few minutes. Here is how.
If they insist and the panel dials out
Stay polite and specific. You are not challenging a policy; you are asking them to store a number in a field they already maintain.
- Ask what number formats the panel accepts, rather than arguing about mobiles.
- If they mention long distance, they are describing a real limit. A dial-out panel only reaches numbers it is set up to call, and the building pays for its line.
- Ask for the answer in writing. A written reason gives you something specific to respond to.
The long-distance point is the honest version of many of these conversations. DoorKing’s manual, for example, has numbers that need an area code or long-distance dialing programmed separately from local ones, and a call outside the local area is long distance on the building’s line. So the safe number to hand over is one that is local to the building. Why that catches so many people.
What to give them instead
A number chosen to be local to your building avoids the long-distance problem, and it can ring more than one phone, which a single landline never could. What each option costs.
BuzzMeBro checks local availability from your postal code before you pay, then gives the apartment a number that rings up to 4 phones for $9.99 a month, with nothing installed in the apartment. Start free.
From our own door
- BuzzMeBro has run on our founder’s own Toronto apartment door since August 2026.
- We only give an apartment a number local to the building’s calling area, because many panels only dial local numbers. We check this from the postal code before any card is taken.
- Switching to our number means the building updates one stored number for your unit and nothing else. Pointing it back at the old number undoes it the same day.
Questions people ask
Can a building require me to have a home phone?
Practically, a building can only need what its system needs: a dial-out panel has nothing for a home phone to do. As a rules question, this guide is general information only. In Ontario, Renting in Ontario: Your rights is the plain-language starting point, and the Landlord and Tenant Board resolves landlord and tenant disputes.
What if the panel really does run through apartment lines?
Then the requirement is genuine and no number will substitute, because the system rings the wiring in your suite rather than placing a call. Ask the building whether it has any plans to change the entry system, because the answer affects every unit.
Should I escalate to the condo board?
Only after the written question has gone unanswered. Keep it to the system rather than the person: a specific technical question is easier for a board to act on than a complaint.
They said mobiles are not secure. Is that true?
A buzzer call from a dial-out panel is an ordinary phone call to whatever number is stored, so a mobile is neither more nor less secure than a landline. The door digit only works on a call the panel itself placed; a stranger dialling your number cannot open anything.
What do I actually ask them to store?
A number that is local to the building. If more than one person lives with you, BuzzMeBro gives the apartment one such number with room for everyone who lives there, so the building only ever has to make this change once.
