Virtual phone number for apartment intercom: what actually works

When you move into an apartment with an intercom, the simplest option is to give the building your cell number. The slightly smarter option is a virtual number — Google Voice, a call forwarding service, or Twilio. But none of those actually solve the problem.

Here's the difference between getting a virtual number for your intercom and actually automating it.

Why Google Voice alone isn't enough

Google Voice gives you a local phone number that rings your real phone when someone calls. For an apartment intercom, that means: building buzzes your unit → Google Voice forwards the call to your cell → you answer and press 9 to open the door.

That's still manual. You still have to answer every call. You still miss deliveries when you're in a meeting. You still get woken up by a USPS carrier at 8 AM. The problem hasn't changed — you've just added a layer.

What you actually want is a number that handles intercom calls automatically: answers them, figures out who's there, and buzzes in the people who should be buzzed in — without involving you at all.

Twilio can be coded to do this, but requires building it yourself.

What about building it yourself with Twilio?

Twilio is the underlying infrastructure that powers BuzzBot (and many other phone applications). You could build an apartment intercom bot yourself using Twilio Programmable Voice — and some developers have done exactly that.

The tradeoff: you're maintaining a webhook server, writing TwiML responses, integrating the Gmail API, handling DTMF responses, and keeping the whole thing running on a cloud server you pay for and manage. It's a weekend project that becomes a maintenance burden.

BuzzBot is the version where someone else already built and maintains that infrastructure — with an iPhone app, Gmail integration, and push notifications already included.
