This is the big problem. "Human names" are not unique enough! In a normal wire-line directory the name is associated with a fixed location, usually an address but at least a city. This can be used as a discriminator among possible name duplications by the querier. Cellphones do not provide the "relay agent" with such fixed, known information to assist in discriminating among customers with the same name. Since cellphones are so mobile there even might only be a country indication. Or were you intending that ALL phones of people with the same name be contacted. Wouldn't this just put the burden on all of the target users to determine the identity of the querier based on....what? And how would any one of the targets determine that she was the intended victim? -- Bill McQuillan <McQuilWP@xxxxxxxxx> _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
