How can I reboot the server with out the root password?

AsteriskNow is not working… It’s 11:20 PM, I’m at home.

I restarted Asterisk, but IAX phone will not register.
I also restarted zaptel.

With SIP registration I get “NO ROUTE TO DESTINATION”

The way to fix this is to wait for the developers to fix it or just reboot the thing, but how with no root or SU password?
