[Synopsis]
Try executing a system command
[Description]
TrySystem(command): Executes a command by using system().
on any situation.
Result of execution is returned in the SYSTEMSTATUS channel variable:
FAILURE Could not execute the specified command
SUCCESS Specified command successfully executed
APPERROR Specified command successfully executed, but returned error code
Old behaviour:
If the command itself executes but is in error, and if
there exists a priority n + 101, where 'n' is the priority of the current
instance, then the channel will be setup to continue at that
priority level. Otherwise, System will terminate.--- in Asterisk 1.4
