How does it work?

 If you just dial an Autonomous System Number, it’ll ring a predefined group of phones within that AS. (example: 42 )  If you dial an ASN and an extension number, it’ll ring the phones belonging to that person. (example: 42*WEW )  Also, well-known extensions for NOC, abuse, routing, SIRT, et cetera.
