This requires MySql 5 or above as it uses triggers.
Asterisk alarm receiver – using triggers, mysql5
This is really rough but it works so far. YMMV.

email me for any help or information.
This code has been shamelessly butchered from wakeup.php (http://www.voip-info.org/tiki-index.php?page=Asterisk+tips+Wake-Up+Call+PHP)

Andy, please don’t hate me.
Please don’t blame Andy for the complete lack of style, it was a quick fix and it works. Andy’s code had much niceness about it which i
removed while developing. I should have put it back and probably will one day.
Flow of events….
1. Alarm panel sends codes to asterisk box
2. Shell script is run by alarmreceiver
inserts alarmcode into alarm_event
triggers output_events creation
3. shell script then looks at output_events rows to see what work it has to do
4. shell script then tries to create call files (this step is also triggered by cron)
If its a call…
1. Plays message “The alarm has triggered”
2. plays site name using flite
3. plays zone, event code etc (read alarm.php for more info)
4. lets the user press 1 to ack. they get 3 calls if its not acked. alarm_calls for limits
eventcmd = /usr/local/ilb/asterisk/alarmproc (or whereever you want to put it)
/usr/local/ilb/asterisk/alarm_calls
alarm-out

update triggers
* alarm_event contains the actual events, a trigger runs to …
** set all the appropriate cols
** insert rows into output_events table based on the triggers table
* areas contains the list of areas for each site
* users contains the list of users for each site
* event_groups is the major headings for each category of events
* event_types is the individual events that can be reported
* site is the list of sites with site codes that you listen for
* triggers is the table that has the alerting rules. pretty much, if its blank, it matches.
* action of call means dial
* action of email means emailalarmproc is called by alarmreceiver
alarm_calls just makes the calls (and is called by alarmproc and crontab)edit alarmproc and alarm_calls
* change server.domain.com.au to your mysql server
* set the username/passwords accordingly
* set callerid appropriately
* edit the sendmail line and adjust the from address
