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.
