Asterisk as a phone system makes perfect sense in a condo. You can get
all the DID's you want and eliminate costs for the owners. You can offer
standard FXO for people who don't care and IP sets for people who want
to "upgrade" to feature sets.
Your door openner is a piece of cake.
1. Create an option in your dialplan only in the "from-access-door"
context that reads DTMF from the called station only.
2. Use this to access an external program to turn on a serial port line
for 10 seconds.
3. This line drives a solid state relay (~$30) so you won't blow the
sink current on the PC port that drives a standard door lock.
A commercial door strike is about $100. The program to run the port is
childs play. Here is a test prog I used for turning on a power hungry
last printer. Change the comments and the sleep time and you're done.
/*
* lpon Lineprinter ON
* *** test program only **
*
* (c) David Cook, 1994
*
* Set signlal lines on serial port to turn on 5vdc
* signal. Used for solid-state relay (low current
* draw on RS232C port) to switch high voltage/high
* current load for printer.
*
* Part of an intelligent print spooler to only power
* on/off high draw printer when required.
*
* Usage: lpon<device> <bits to set>
* For example, lpon /dev/cua4 4 to set bit 3 on
* port /dev/cua4.
* "4" = 00000100 or bit 3 which is DTR
* "2" = 00000010 or bit 2 which is RTS
* "6" = 00000110 or both DRT& RTS

[asterisk-users] Fwd: Re: Asterisk as a Condo door opener/intercom
Hi. To open the door I'm suggesting you to use Arduino if you can't have a PC near the door opener contacts. Arduino is something useful for implementing this type of networked embedded stuffs. It's not so expensive and easy to use for people familiar with C, C++ and a little bit of electronics. You can find it worldwide by e-commerce and is very well supported by a lot of open sourced libraries. If you stack an Arduino UNO and an Ethernet Shield SD you'll have a small embedded solution providing you at maximum of four hw based TCP sockets that you can use for implementing, for example, a little web server. The digital input/output pins could be used (if properly buffered by a transistor) to drive a relay to be placed in parallel with the door opener pushbutton. To have the best reliability you can use the tricks suggested on the pachube website, where someone suggest to drive the Ethernet shield reset pin at regular intervals. At the asterisk level I've implemented something similar to what's explained by David. The only difference is that, in order to open the door, I've used the CURL application to generate a suitable HTTP get to the IP address associated to the Ethernet shield on top of Arduino.
