Name

TrySystem() — Tries to execute an operating system command

Synopsis

    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.
