- While trying to make a credit card call to a persistently busy number
- recently, after typing in the card number for the n-teenth time, I
- wondered if SS7 protocol would allow the calling exchange to "look
- ahead" at the called number and inquire if it is (at that instant)
- busy, before prompting me for the card number. Of course, I might
- still get a busy if either the line became busy after I keyed in the
- credit card number, or if the response to the query didn't make it
- back to the originating exchange in time. The advantage (to me) would
- be not having to repeatedly pound in the billing. The advantage
- (small) to the carrier would be not having to do the credit card
- verification, and perhaps getting the line on which I'm calling free a
- bit quicker. If the call in question were third party bill, or
- collect, the savings could be a lot greater.
