the buzzer system may not wait 'on the line' very long because it's expecting to receive either a DTMF tone for unlock door within 5 to 15 seconds of the call being answered, or a disconnect such as if a person in their condo is holding a POTS phone and just hangs it up when an unknown person buzzes them, denying entry.
