You're totally right — "legacy" probably wasn't the best word. In a lot of cases, even the setups that call your phone are more functional than what most buildings still have: just a mic, speaker, and a few buttons, or a hard-wired landline. I think what I really meant was that there's a lot of untapped potential for automation and smarter access, even in those "more advanced" systems. Long term, I'm also exploring a hardware solution to modernize those even further — something that could work with the more basic setups and bring them up to speed with features like remote unlock, access logs, and scheduled access, too.
