Maybe that is why my phone bill has always been so high, as my home phone
number also has a '9' in the 4th digit!  ;-} ;-} ;-}

I also know of at least two other non-pay_phones that have a '9' as the 4th 
digit, so I would certainly not rely on using that as a positive indication 
that the caller is at a pay phone!

Just thought I would point this out before someone designs their automatic
caller-id phone system to flag all "4th digit '9's" as pay-phones. Thanx.
