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 , whereas the System( ) application will return -1 if it is unable to execute the system command.
