A PBX administrator must keep on top of any new prefixes in the NPA to make sure they are programmed for the right route. In this area, one must keep on top of new prefixes in 408 AND 415, since there are prefixes being added in 415 that are local to this part of 408 (and visa versa). I get a quartarly listing of prefixes from PacBell. In the case of COCOTs, as usual, the situation is pot luck. The general rule is that the phone's programming is out of date, and when you try to call someone with a brand new phone number, the phone won't allow it. John Higdon | P. O.
