My townhome complex had one of those call boxes at the front gate. When Doordash/FedEx/the cleaners/the in-laws/etc arrived they would have to call me from the call box and I'd have to answer it and listen to garbled audio to figure out who it was and press 9 to open the gate. It was kind of a pain, so I made a Twilio app to answer calls from the call box.
I set up custom entry codes that I could hand out to anyone. Everyone got their own code, and it would text me whenever someone used a code so I'd instantly know who was coming. The text conversation was my timestamped access log. I also put time constraints on some codes so e.g. Doordash couldn't open the gate in the middle of the night, or I could set up a temporary access code for a party, and I rotated codes too, with text notifications if an outdated code was used.
I thought about making a paid app out of it, but it just didn't seem worthwhile. I didn't expect that many people would want to pay for it. For a while I was excited about a YC startup called Doorport that was going to make a hardware device that you'd install inside those dumb call boxes and make them smart with all sorts of cool features, better than my Twilio hack. But I think they pivoted to a much less interesting pure software thing and then got acquihired.
