The IANA RFC3219 listing shows who the real early adopters are in the SIP namespace. Dorks who really want to call me will be able to dial my extension (yeh – right – like I'm going to publish that on the weblog!) at phonehost.slingerlands.com. (No .. it's not really "phonehost" either)
See the ISN cookbook for more on this and how to get your own.
