Your buzzer is dialling a number that no longer exists

BuzzMeBro sells a paid fix for buzzer problems. This guide covers the free options too.

A buzzer that reaches a not in service recording is dialling a number that was cancelled, often an old home phone or a previous tenant number nobody removed from the panel. The panel placed the call and the network answered with a recording, so the stored number is the fault. Property management has to replace the entry for your unit, and the number they store next should be one you control.

Say a friend presses your unit, hears a recording about the number being out of service, and texts you about it. That recording is the most useful clue the whole system can give you.

What the recording tells you

A telephone entry panel works as an autodialer: a visitor enters your code and the panel calls the phone number stored for your unit. Mircom’s TX3 manual describes exactly this. A recording means the panel dialled and the phone network answered for a number that no longer works.

That is different from silence, which usually means the call cannot be completed from the panel line at all. The silent version.

What the visitor hears, and the likely cause
At the panelLikely cause
A not in service recordingThe stored number was cancelled
A call cannot be completed recording, or nothingThe panel cannot reach that number, often because it is not a local call
A stranger answeringThe panel still holds a previous tenant number that now belongs to someone else
VoicemailThe right number, filtered or unanswered

Where the dead number came from

Often a home phone belonging to somebody who moved out and cancelled it. Cancelling a phone line does not tell the building, and a lease ending does not update the panel.

Sometimes it is your own old number, still in the panel after you dropped a line you were keeping for the buzzer. Doing that in the right order.

Getting it replaced

  1. Confirm it yourself at the panel Enter your own unit code and listen. Write down exactly what the recording says.
  2. Email property management Use the wording below, and give the number you want stored.
  3. Ask for written confirmation Ask them to reply once the panel is updated, and keep the reply.
  4. Test from the lobby afterwards Enter the code, answer, and open the door once, so the whole chain is proven.

The full version of that request.

What to put in instead

A number that will not go dead without you knowing, and ideally one that does not belong to a single person who might move out and cancel it. That is the failure you are living with now.

BuzzMeBro gives the apartment a number of its own, local to the building, ringing up to 4 phones for $9.99 a month. The phones behind it change when people do, and the number on the panel stays put. Start free.

From our own door

  • BuzzMeBro has run on our founder’s own Toronto apartment door since August 2026.
  • 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.
  • A buzz rings the people on the apartment who are set to ring, up to 4 phones at the same time, so the number on the panel no longer depends on one person keeping their line.

Questions people ask

Is the buzzer broken?

Probably not. A not in service recording means the panel placed a call and the network answered for a number that no longer works. The fault is the number stored for your unit.

Can I find out whose number it was?

Property management can see the directory entry. It is rarely worth chasing, since what matters is replacing it.

How urgent is this?

More than it feels. Every visitor and courier hears a recording that says your number does not work, and nothing tells them how else to reach you.

It happened right after I cancelled my home phone.

Then the panel was holding that number. Have the building store a working one, and next time arrange the replacement before the cancellation rather than after.

How do I stop it happening again?

Store a number that belongs to the apartment rather than to one person or a service you might cancel. With BuzzMeBro the phones behind the number change freely and the number itself stays put.
