The alarmreceiver.conf file is used by the AlarmReceiver( ) application, which allows Asterisk to accept alarms using the SIA (Ademco) Contact ID protocol. When a call is received from an alarm panel, it should be directed to a context that calls the AlarmReceiver( ) application. In turn , AlarmReceiver( ) will read the alarmreceiver.conf configuration file and perform the configured actions as required. All parameters are specified under the [general] heading.
The sample configuration file will contain the current settings for this application and is very well documented.
