To Dial For!

I’m pretty impressed with these Dial by Name Directories you get when you call some companies. You call a company, no once answers the phone, so you eventually dial “1” to use the Dial by Name Directory. A voice tells you to dial the first three letters of the person’s first name. These directories work pretty well, but there can be issues:

•          What if the person you're trying to reach spells their name wrong? If Isaiah spells his name Isiah, you could be in trouble.
•          If the person’s name is, say, Tommy, do you type Tom or Tho?
  
•          What if they have a two letter name? Is this process fair to Bo and Cy? Does Ed get any messages? 
•       What do you do with the AJ’s and the JR’s? Do we need to know their middle initials? 

And what’s with dialing “1” for the Dial by Name Directory in the first place? Wouldn’t it make more sense to dial “A”? Is that asking too much?
