Your buzzer says "call cannot be completed". Here is what that means.
A buzzer that says the call cannot be completed is playing a recording from the building phone line, not from your phone. The lobby panel line is usually restricted to local calls, so a number from another calling area never rings. A spam block sounds different: the panel rings, then reaches voicemail. The fix is a number local to the building, which BuzzMeBro provides.
In December 2024 a Public Mobile customer posted on the carrier community forum. Their building buzzer would not reach their phone. The panel said the call cannot be completed.
They asked their carrier, which is where most people start. It is usually the wrong place to look. When the cause is the building line, the carrier never receives a call, so it has nothing to block and nothing to fix.
Where does the "call cannot be completed" message come from?
When a visitor presses your unit, the lobby panel places an ordinary phone call. It dials on a phone line the building pays for. If that line is not allowed to place the call, the phone company plays a recording back down the line. The visitor hears it through the panel speaker.
The wording depends on the phone company. "Your call cannot be completed as dialed" is the common one, often followed by "please check the number and dial again".
Buildings usually restrict the panel line to local calls. A line that can dial anywhere will sooner or later dial somewhere expensive, and the building pays that bill. So a number from another calling area is refused before the call leaves the building line. Your phone does not ring. There is no missed call and no voicemail. How the dialling chain works.
How do you tell a line restriction from a spam block or a wrong directory entry?
Three different faults get reported as "my buzzer does not call me". They sound different at the panel, and they leave different traces on your phone.
| What the visitor hears at the panel | What your phone shows | Most likely cause | What fixes it |
|---|---|---|---|
| A recording: "call cannot be completed" | Nothing. No ring, no missed call, no voicemail | Your number is long distance from a panel line restricted to local calls | A number local to the building goes on the panel |
| The same recording, and your number is local to the building | Nothing | The directory entry is mistyped, short a digit or missing the area code | The building re-enters your number |
| Normal ringing, then your voicemail greeting | A voicemail or a missed call, sometimes nothing | Carrier spam filtering, or a setting that silences unknown callers | Save the panel line number as a contact |
| Normal ringing, then a stranger answers | Nothing | The directory still holds the number of a previous tenant | The building updates the entry |
| A recording: "not in service" | Nothing | The stored number has been disconnected | The building updates the entry |
The quick split is ringing. If the panel rings before anything else happens, the call left the building and the problem is further along. The causes of a buzzer going to voicemail are a separate list. If a recording cuts in before any ringing, the call never left the building line.
How do you test the buzzer yourself from the lobby?
- Buzz yourself Go to the lobby with your phone in your hand and the ringer on. Press your own unit code the way a visitor would.
- Listen to the panel Ringing means the call left the building. A recording before any ringing means the building line refused the call, or the stored number is wrong.
- Check your phone Look for a missed call, a new voicemail, or an entry in your blocked or filtered calls. Any trace at all means the call reached your carrier, and a line restriction is ruled out.
- Have the stored number read back Ask the property manager to read out the number stored against your unit, digit by digit, including the area code. More ways to find out what number your buzzer calls.
- Ask one question about the line Ask whether the entry panel line can place long distance calls. If the answer is no and your number was issued in another city, you have found the cause.
Why is your number long distance when you live in the building?
A mobile number belongs to the place it was issued, not the place you live. Move across the country and a call to your number is still a call to your old city. You never notice, because mobile plans treat the whole country as one zone. A building line on a basic local plan does not.
The area code alone does not settle it. Local calling is decided by the exchange a number was issued in. A number can share an area code with half your city and still be long distance from your building. A 905 number issued in Hamilton is a long distance call from a Toronto line.
This is why the fault lands on newcomers, students and anyone who moved for work and kept their number. There is more detail in out-of-province numbers on Toronto buzzers and which GTA area codes a Toronto panel can reach.
What if your number is local and the recording still plays?
Then the directory entry is the suspect. The panel dials exactly what was typed into it. One wrong digit, a missing area code or a stray leading 1 can each produce the same recording.
This one is free to fix, and you do not need BuzzMeBro for it. Ask the building to re-enter your number as ten digits, then test it while you stand in the lobby. How to get the number on your buzzer changed.
What fixes a buzzer that cannot complete the call to a long distance number?
The panel line will only dial local numbers, so the panel needs a local number. There are four ways to give it one. They are listed here by how well they solve the problem, not by price.
A local number for the apartment that rings your own phones: fixes it, for a monthly cost
BuzzMeBro gives your apartment its own local phone number. You hand that number to the building once, and they store it in the lobby panel like any other number. When a visitor buzzes, it reaches your phone as an ordinary inbound call, whatever city your own number is from. There is nothing to install, and your mobile number does not change.
Every phone registered to the apartment rings at the same time, up to 4 phones. Whoever answers first gets the call and can open the door. So a roommate or partner with an out-of-town number is fixed by the same change. The door-open digit is usually 9, but it is set per building.
The limits are plain. It costs $9.99 per month or $95.00 per year, per apartment and not per person. A local number is checked at signup, and a building with no number available goes on a waitlist. The subscription is the only thing BuzzMeBro is paid for, and its privacy policy commits to never selling customer data or using it to train AI models.
A free number from a calling app: fixes the local call for one person, but the door may not open
This is the advice most carrier forums give. Get a free local number from a calling app, give that number to the building, and forward it to your mobile. If you live alone and the local call is your only problem, it can be the right answer.
Know what it costs you in other ways. It rings one phone. The door opens because a keypad tone travels back down the call, and some services re-encode the call audio on the way. When the tone does not survive the trip, you get the call and cannot open the door. Why pressing 9 sometimes does nothing. Read the inactivity rule too. Some free numbers are taken back when they sit unused, and a buzzer number is one you never call from.
Changing your mobile number to a local one: fixes it, and costs you the number everyone has
Most carriers will swap your number for a local one. The buzzer works once the building stores the new number. Then you spend a month telling your bank, your family and every login that texts you a code.
Asking the building to allow long distance on the panel line: usually a no
Some buildings can do this. You are asking a property manager to accept open-ended charges on a shared line for the sake of one unit. Expect a polite refusal. A landline in your unit would be local too, and it means a monthly bill for a phone whose only job is opening a door.
If the recording is what your visitors hear and your number is from somewhere else, the panel needs a local number. BuzzMeBro gets it one without changing yours. Check your building for a local number, or see how the buzzer services compare.
Questions people ask
Is my carrier blocking the buzzer when it says the call cannot be completed?
Usually not. In most cases the recording plays on the building phone line before the call reaches your carrier. Your carrier cannot see that call, so it has nothing to unblock. A carrier block sounds different: the panel rings normally and then reaches voicemail.
Why does the buzzer work for my neighbours and not for me?
Your neighbours have numbers that are local to the building. The same panel on the same line reaches those without trouble. Your number is refused because the panel line is not allowed to dial long distance.
Will adding a 1 in front of my number on the panel fix it?
Only if the building line is allowed to place long distance calls, and most are not. On a restricted line the 1 changes nothing and the same recording plays. Ask the building whether the panel line has long distance before anyone reprograms your entry.
How can I test whether my number is long distance from the building?
Press your own unit in the lobby and listen. A recording before any ringing, with no trace on your phone, points to the building line. Then ask the property manager whether the panel line can dial long distance. Calling yourself from another mobile proves nothing, because mobile plans ignore long distance.
Do I have to change my phone number to make the buzzer work?
No. The number on the lobby panel can be a separate local number for the apartment. BuzzMeBro provides one and rings up to 4 phones at the same time when a visitor buzzes. Your own mobile number stays as it is.
