Kinda, sorta. 7-digit local dialing is supposed to have been phased out,
with all NANP numbers represented as 1+NPA-NXX-XXXX.
But, speaking of en-banc dialing on cell phones, do you find that
users typically enter the 1? I certainly don't. 10-digit is the most
common form I see.
Cell phones seem to be very forgiving.
NPA-NXX-XXXX
1-NPA-NXX-XXXX
011-1-NPA-NXX-XXXX
all work. Out of habit, I generally dial the 1.
We don't support 7 digit (we killed it at the same time Ma Bell did in
our area).
I think this is pretty much the case for most of the NANPA region, but
it's handy if you aren't in an overlay area.
This means that after your trunk access 9, you should expect a 1
(followed by ten digits for a regular phone number), a 0 for operator or
011 international, or a three-digit code starting with 2 or 9 that until
this week always ended in 11.
Program 88 as a sequence to re-insert the stripped 9 and send
immediately on trunks accessed by a 9, just like you do with 11.
The problem is, right now, you are right. If someone dials 9 then 8,
they get fast busy immediately (because there should have been a 1).
But after the change you mention, if they are trying to dial the very
common toll-free NPA 888 and forget the 1, they will instantly be
talking to the suicide hotline.
But if they can't dial 9-8[anything] now and never have been able to,
they aren't likely to start doing so trying to reach toll-free 9-888 in
the future.
And by failing after 9 then 8, you're breaking Dig Alert. Likewise
you're probably breaking the other N-1-1 codes as well such as 7-1-1 for
TDD, etc.
