Does Buzzerful work with any apartment buzzer?

Buzzerful only works over phone line based systems.
 

If your current apartment buzzer can ring any phone number you choose (a landline, or a phone number), then yes!
 

If your building has an old style button buzzer, or a seperate phone just for the buzzer, unfortunately Buzzerful does not support your building at this time.  We are on the look out to find a way to make this happen in the future.
