TrySystem( )

Tries to execute an operating system command

    TrySystem(command)

 

Attempts to execute a command in the underlying operating system. If the command itself executes but is in error, and if there exists a priority n+101 (where n is the current priority), the execution of the dialplan will continue at that priority level.

This application is very similar to the System( ) application, except that it always returns 0, whereas the System( ) application will return -1 if it is unable to execute the system command.
