Vertical services codes are defined by NANPA to let customers (somewhat) control their phone service. They're mostly of the form
*XX.Service code *67 blocks sending caller-id, and *82 unblocks if your cid is blocked by default. In the past, when I've used them, I dial
*82, get a second dial tone, then call NXX-XXXX or 1-NXX-NXX-XXXX.I just switched from copper to fiber at my local phone company, and now it's *67NXX-XXXX or *67NXX-NXX-NXXX or *82NXX-XXXX or
*82NXX-NXX-XXXX, no second dial tone, no 1- before 10D. I guess they use a timeout to tell 7D from 10D.This seems wrong, but I can't find a spec beyond what's on the NANPA web site. Is there a more complete spec anywhere?
I am NOT, repeat NOT asking anyone how you personally think it should work, I'm asking if there's a written standard I can point to. TIA.
