API commands from Dialplan
All commands (APIs) you can execute from cli in the FreeSWITCH console are also available to be used in dialplan.
Many API commands are provided by mod_commands (search for it in http://freeswitch.org/confluence), but usually all modules add their own API commands you can execute from the console command line. From the console, type "help" for a quick overview.
The general form to execute an API command from dialplan is:
${api_command(argument01 argument02)} You may use the "set" action, and assign to a channel variable (that you maybe will not use) the string returned from the console command line.
API commands' arguments are between parenthesis and separated by spaces; if there are no arguments, use empty parenthesis.
The third action line of this example extension will try to unload mod_verto from FreeSWITCH, and the fifth action line will give us the SIP dialstring to call the caller (if the call was originated by a registered phone):
<extension name="API">...
