Syntax of call files
Specify where and how to call

Channel: : Channel to use for the call.
CallerID: «name» Caller ID, Please note: It may not work if you do not respect the format: CallerID: «Some Name» <1234>
MaxRetries: Number of retries before failing (not including the initial attempt, e.g. 0 = total of 1 attempt to make the call). Default is 0.
RetryTime: Seconds between retries, Don’t hammer an unavailable phone. Default is 300 (5 min).
WaitTime: Seconds to wait for an answer. Default is 45.
Account: Set the account code to use.
If the call answers, connect it here:

Context: Context in extensions.conf
Extension: Extension definition in extensions.conf
Priority: Priority of extension to start with
Set: Set a variable for use in the extension logic (example: file1=/tmp/to ); in Asterisk 1.0.x use ‘SetVar’ instead of ‘Set’
Application: Asterisk Application to run (use instead of specifiying context, extension and priority)
Data: The options to be passed to application
Set: Can now also write to dialplan functions like CDR()
AlwaysDelete: Yes/No — If the file’s modification time is in the future, the call file will not be deleted
Archive: Yes/No — Move to subdir «outgoing_done» with «Status: value», where value can be Completed, Expired or Failed.
