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 -------------- next part -------------- An HTML attachment was scrubbed...

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.

Not really very odd. Many small business have door intercoms with lock releases that are either built into or accessories to ( non-Asterisk ) Business phone systems you might look to Viking electronics or similar telephone accessory suppliers for something that will work for your install "inexpensive" is relative however.

The serial port line drives a transistor, which drives a large relay, which applies power to the (pre-existing) door solenoid. Fairly trivial if you know how, hard otherwise :-) - Mike
I've done a remote door unlock system in the past. The customer had an existing magnetic lock system that utilized push buttons on the wall to release the magnetic locks on the doors. They already had this system, and the associated door controller. I used an APC AP9210 Master Switch network power controller to solve the problem. I plugged the power brick for the door controller into the AP9210, put the AP9210 on the network, and wrote a script that caused the device to cut power to the door controller for 5 seconds by setting an SNMP variable. I coupled that shells script with some dialplan logic that asked the caller for a pin, then using the callerid(num) value as a username, checked the username/pin combo against a database.. If the combination passed, the shell script was called. If it didn't, I looped back to the request for the pin, for up to 2 more times, then disconnected the call. I know Cyberdata has some SIP based door intercoms that have lock relays built in, as well. I have no idea what the cost for them is, though.

Hello, We did something like that in the past (but for 1 company, but it shouldn't be really different). The easiest solution for us was to use a door opener that could work with almost any "normall" phone connection and use a Linksys pap2t or something similar.
