-
- Real payphones have calls charged and routed in the CO, which has the
- advantage of real-time access to supervision info, not to mention
- definitive digit decoding (i.e., if the CO can't decode it, you can't
- call there.)
-
- I do agree that COCOT manufacturers should be required to understand
- all valid digit patterns if they attempt to decode them at all. I've
- noted in Telecom that the telco pay phones at the Newark and
- Philadelphia airports have a COCOT-like hack in which they look for
- calls to the "waiver areas" across the Hudson and Delaware rivers,
- respectively, and prepend the appropriate 10XXX to route the call via
- the telco's own LD service rather than AT&T. BUT, and this is a big
- but, if you dial your own 10XXX or anything else except a non-10XXX
- call to the waiver area, the phone sends through exactly the digits
- you dialed and never disables the tone pad.
