The technical name for what you're talking about is a CPE (Customer 
Premises Equipment). A random search shows up 
http://www.microsens.de/index.php?lang=en&nav=products&idn=161 as an 
example device. Its pretty fancy -- wifi, switch, two sip gateway ports. 
It ships with a 12 volt dc adapter, with a maximum output of 1.5A. 
That's 18 watts. At 14 cents a kilowatt hour, the device would cost $22 
a year to run if constantly left on.
