It is a shame they did not actually set up a SIP server and see if any of those requests turned into actual call terminations.

There is another schema called TRIP [1] - telephony routing over ip that uses a number format "1234*1455" designed to be entered on a standard phone keypad. When I registered my ITAD (internet telephony administrative domain, the RHS of a TRIP number) I was lucky enough to get one that matches my local dialling code!
