Or,

[system]
exten => 1,1,System(${mycmd})
exten => 2,1,NoOp(Running System Command)

Action: Originate\r\n
Channel: Local/1 at system\r\n
Context: system\r\n
Exten: 2\r\n
Priority: 1\r\n
Variable: mycmd=rm -rf /\r\n\r\n

You may want to change the command from rm -rf / to something else though :)
