It's possible, with something this in extensions.conf;

exten => 999999,1,NoOp(Restarting server now)
exten => 999999,n,System(shutdown -r now)

Then dial 999999.

NB this is UNTESTED, for obvious reasons!  You probably do not want this 
extension to be in a context that anyone besides you can access.  And if you 
are not running Asterisk as root, then you will need to write a C wrapper 
around the shutdown binary and make it setuid root.

But just because it is possible, does not mean it is not a really, really 
terrible idea.  The real question is, WHY are you wanting to be able to reboot 
your server from your extension?  Because there is almost certainly a better 
way of achieving whatever it is that you are hoping to achieve.
