Configuring Automatic Calls in Asterisk

Asterisk can automatically make a call if you put a .call file in the (default) /var/spool/asterisk/outgoing/ directory. If the date of the file change is greater than the current one, the call will be made on or after this time.

For automatic calls, the module must be loaded, it must be registered in modules.conf or autoload=yes must be specified.

I’ll give an example of the contents of the file:

Channel: SIP/goip4/10670000000
Application: Playback
Data: file1
MaxRetries: 5
RetryTime: 60
WaitTime: 30

Briefly describe what I said in it:
Channel: SIP/goip4/10670000000 (channel for an outgoing call, in my case the first SIM card on the goip4 gateway will be used and the number 0670000000 will be dialed)
Application: Playback (application that you need to execute when you call, in my case, Playback to play an audio file)
Data: file1 (data for the application, since Playback is started, file1 is the name of the file being run, in my case I put the file here /usr/share/asterisk/sounds/ru_RU/file1.ulaw)
MaxRetries: 5 (the number of attempts after which the call will not be considered successful, the default value is 0, the count starts from 0 – this is a one-time call)
RetryTime: 60 (time in seconds between call attempts, default 300 (5 minutes))
WaitTime: 30 (call waiting time in seconds, default 45)

You can also specify:
Context: NAME (context name from extensions.conf)
Extension: NAME (extension name of extensions.conf)
Priority: (priority number from which to start execution)
Archive: Yes/No (Yes means transferring the .call file to the /var/spool/asterisk/outgoing_done/ directory after the call is made)
AlwaysDelete: Yes/No (do not delete the file if the modification time is longer than the current one)

For example, you can move a ready .call file using rsync at certain events, after which the call will be made:

rsync -avh /scripts/zabbix/alert.d/ /var/spool/asterisk/outgoing/
