While an 800 number call is always routed over a particular carrier depending on the prefix dialed, a 700 call can go to different places for the same number depending on the LD carrier SELECTED. The "check your default carrier" is a perfect example. The number "700 555-4141" goes to a different place depending on what carrier is selected by the caller. If you don't select a carrier, then it goes default -- and the recording provided by the particular carrier will tell you where you ended up. If you prefix that number with a 10XXX code, you will get the recording for the carrier you selected. Calls to 700 numbers can be free, or charged at a rate determined by the carrier. If you don't have an account with a particular carrier, then you will be "casual billed" in the same manner as if you had dialed any call preceded by 10XXX. John Higdon | P. O.
