[comp.dcom.telecom] recording from another area code/long-distance call to ANAC

David_W_Tamkin@cup.portal.com (08/25/88)

Lars Poulsen, in Digest v8, #122, reported the following when he tried
calling my local ANAC code from his location:

 ------------------------------
I tried this, from my GTE line (805) 682-xxxx (Santa Barbara, CA).

290 yields (ring, ring, redirect, recording:) "We're sorry ... cannot be
completed".  1-312-290-1234 yields (redirect, recording:) "Your call cannot
be completed ... 818-4T".  Since 290 does not require 7 digits before the
rejection from the local switch, it seems like this prefix gets special
handling (or is that true of unassigned prefixes in general ?

The long distance call get rejected in the LATA router. Wouldn't it be
nifty if it had gone thru ?.

 ------------------------------
Dave Cantor got a similar recording from an intermediate area code when he
tried calling Weathertrak in New York from New Hampshire, as he said in
Digest v8, #128:
 ------------------------------
When I dialed it directly (1-212-540-3000) I got rejection messages from US
Sprint, from MCI, and from AT&T indicating they could not complete the
call.  The AT&T message was "Your call cannot be completed as dialed.
508-2T."   Funny, I was calling from a New Hampshire telephone (NPA 603),
but got an area 508 message!

[ ... ]

One question:  Why would I get a message from 508-2T when dialing from an
area 603 telephone?
 ------------------------------
======
Since 290 [Centel's three-digit ANAC] is not a valid prefix in area code
312, Lars's long-distance company couldn't find it in its database.  Surely
Centel's ANAC facility here couldn't be expected to report the number from
which it received a long-distance call!  Patrick Townson cannot even call
it from his location in Illinois Bell's part of area code 312.

Both in his case of calling an invalid prefix in 312 from 805 and in Dave's
case of dialing a restricted prefix in 212 from 603, the rejection message
came from a third area code.  I imagine that Lars's call got routed as far
as area code 818 (a bit out of the way geographically but not unreasonably
so) and Dave's call as far as 508 (not out of the way at all) because their
long-distance providers had their switching centers and databases of
reachable prefixes in those locations.  Lars's call to a nonexistent prefix
in 312 was rejected by a machine sitting in area code 818 and Dave's call
to a restricted prefix in 212 was rejected by a machine sitting in area
code 508, so those were the area codes in the announcements.

This gets even better !   I tried dialing 1-212-540-3000 from work, where we
us MCI (ugh!), and got the following message everytime:

	"We're sorry.  MCI does not complete calls to 976 at this time. 2BZ"

WHAT !?   I didn't dial a 976 number !!  What's worse is: what if they *had*
completed it ?   I could have been charged out the whazoo for what I thought
was a normal long distance call.

What is going on here ??  Obviously there is some number translation going
on here but who said they could do it to a more expensive number without
telling me !?
