Synopsis

    System(command)

Executes a command in the underlying operating system. This application sets a channel variable named SYSTEMSTATUS to either FAILURE or SUCCESS, depending on whether or not Asterisk was successfully able to run the command.

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