Building intercom not calling a resident? What to check
For property managers and building operators. Applies to ButterflyMX, DoorKing, Mircom TX3 and most other intercoms.
The quick answer
If one resident isn’t getting calls, check their listing first: the phone number, the app login or the unit. If no one is getting calls, the intercom’s phone line, cellular connection or internet is usually down.
We’ll do it for you
We can update your directory for you and check the intercom remotely where it allows it, or on site.
