This isn't really solving a problem. Phone numbers are already unique, so why replace with another unique based system that has a one to one correspondence?

I'd really like to see something like DNS. You can register a "phone number" or "phone name", upon calling something, it sends a lookup to your phone provider, which then provides a lookup to whatever server houses the data for said name which resolves a unique name or series of characters (not limited to alphanumeric increasing combinations) that responds with data that the phone can digest and create an active connection. Imagine being in control of your own data, who can call you, what sort of data a subscriber can obtain when calling you, etc. Sort of an app.net for your own contact info.
