Basically, any door control system that works with DTMF tones should work - in theory. You will probably need to play around with the length of the DTMF tones, and maybe also with the level.

Hi all, I have had (what I consider) an odd request. The installation I'm working on now is an office on a multi-floor building. They 're looking for some kind of solution with the phone system to provide door control. We are a non-profit so of course I'm looking for something VERY inexpensive. I'm sure /someone/ has done something like this. I'd appreciate any ideas. Cassius Smith
