The double op-divert, and more - By Captain B
|
|
|
|
By this point, most phreakers have probably at least heard about
|
|
op-diverting, if they don't already know how to do it. But, for a while, I
|
|
had wondered about the possiblity of doing a double op-divert. In which
|
|
case, you dial into a PBX (Private Branch eXchange), dial out to 1010 ATT
|
|
0, then dial a 10 digit number from there (Including toll free numbers).
|
|
Well, I can tell you for certain that at least one corporate voice mail
|
|
system allows for such a thing. It's the Altigen voice mail system. But,
|
|
unfortunately, you don't seem to run across these all that often. And, it
|
|
seems like It's not uncommon for this VM system to only have the ability
|
|
to dial out via the admin's voice mail box. Which, in my experience so
|
|
far, has always been at extension/voice mailbox number 500, with a
|
|
passcode of the same. To do the double op-divert, first log into the VM
|
|
box, hit # (pound) to start the dial out proceedure, then dial the outside
|
|
line access digit, (which is a 9) plus 1 and the 10 digit phone number.
|
|
And, in the case of the double op-divert, it goes like this: 9+ 1010 288
|
|
00. And, yes that's not a typo. The 1 after the 9 in this case is dropped.
|
|
(Otherwise, the PBX would recognize what you're dialing as being "911").
|
|
And, you have to dial 2 zeros after ATT (288) instead of the usual single
|
|
zero. Speaking of which, that double zero technique also works even when
|
|
you're just dialing straight through normally to AT&T and other "dial
|
|
around" carrier access codes on phone lines. (At least it works here for
|
|
me, but it could be different where you are). In fact, on COCOT payphones,
|
|
it can even help speed up the time you wait for the computer inside the
|
|
COCOT to start processing (or, should I say, re-dialing) all your 1010
|
|
Carrier Access Code-type calls. Although, there are some COCOTS that won't
|
|
accept 1010 numbers dialed in such a way, and it'll have you redial over
|
|
again. Also, from standard fare fortress Verizon and RBOC (Regional Bell
|
|
Operating Companies) payphones, hitting # (pound) after 1010 XXX 0 will
|
|
put the call through a bit faster as well. Well, at least this is a method
|
|
that works here where I am. But, I know full well that sometimes subtle
|
|
differences in phone switches, and other CO (Central Office) phone
|
|
equipment can change how things work from place to place. Including even
|
|
with 2 different COs in the same town sometimes. By the way, AT&T also has
|
|
a 2nd 1010 number many don't seem to know about or use as much as 1010 288
|
|
0. The second one is 1010 732 0. And, for a while at one point, AT&T also
|
|
had 1010 779 0. All work the same. Still yet one more way to access AT&T
|
|
is through 00. (As long as AT&T is the long distance provider for that
|
|
particular phone line). On payphones, the bottom instruction card will
|
|
show who handles long distance calls for that payphone. But, sometimes
|
|
this info Isn't accurate, or the bottom instruction card may be missing,
|
|
or defaced too badly to be able to read well enough. In which case, just
|
|
dial either 1-700-555-4141 or 1-700-555-1212 and, after a moment, you'll
|
|
hear who the long distance provider is for that given phone line. I've
|
|
tried this method on PBXs to try to find out who the long distance
|
|
provider was for their phone service. But, so far, I've yet to find a PBX
|
|
that recognizes 1-700 numbers as valid. But, I have found that if you get
|
|
the ANI passed by the PBX by dialing an ANAC (Automatic Number
|
|
Announcement Circuit, which will say back the number you're dialing from),
|
|
then use the VM system's PBX to dial the PBX's area code + 700-1212,
|
|
you'll hear who the local service provider is for them. Here's one ANAC
|
|
you can use: 1-866-My ANI is. By the way, I don't know if it would help
|
|
screw up ANI from being passed properly, but you could always use a PBX to
|
|
dial that company's own local or toll free number back again, log into
|
|
another voice mailbox on the same VM system, and dial out via the 2nd VM
|
|
box to whatever number you want to call. To dial into the company's
|
|
corporate voice mail again via their local number, simply dial the number
|
|
read back to you via an ANAC. That local number is the number "behind" the
|
|
toll free number, as It's said to be. Since, most toll free numbers are
|
|
nothing more than numbers that forward your call to some standard 10 digit
|
|
phone number somewhere. (Although, there are some "dedicated" toll free
|
|
numbers that aren't connected to any 10 digit phone number like that).
|
|
Getting back to the double-op divert method, you could also dial into 1010
|
|
ATT 0 or 1010 732 0 to perform an emergency interrupt if the person you're
|
|
calling doesn't have call waiting service, and just won't get off the
|
|
line. In which case, you have to talk to a live AT&T operator, and ask
|
|
them to place an emergency interrupt call for you. (Also known as
|
|
"Emergency interrupt with call completion"). They'll ask you for your
|
|
name. So, be ready with a fake name, if you'd rather the person you're
|
|
calling not know who you are. And, yes, there are special charges for them
|
|
to do emergency interrupt, so you may want to think twice about doing it,
|
|
since if the company checks their phone bills, they'll see the charges,
|
|
know something is up, and probably change either their toll free phone
|
|
number, local phone number, or perhaps even both. In which case, you won't
|
|
have that corporate voice mail's PBX to dial out on anymore. So, always
|
|
think about your actions, and the effect it may have before-hand. By the
|
|
way, don't forget that It's possible to do op-diverting via live
|
|
operators. But, if It's a toll free number you want them to place for you,
|
|
don't expect them to unless you say that you're visually impaired, and
|
|
need help dialing the call. Even then, I've found a number of telecom
|
|
compnies that just won't, or can't do it. The only exceptions I can think
|
|
of off-hand are Verizon operators (via 101 6963 0) certain local RBOC
|
|
operators, and Global Crossing. Global Crossing can be reached at 1010 211
|
|
0, which passes along an ANI of a disconnected number in the 505 (New
|
|
Mexico) area. Probably Global Crossing may have another 1010 number I'm
|
|
forgetting, or don't know about as well, since many telecom companies seem
|
|
to have at least more than one 1010 number. And, some have also been
|
|
setting up their carrier access numbers in the 101 5xxx and 101 6xxx
|
|
ranges. So, search around, if you like. And, as always, have phun, and use
|
|
your head as much as possible.
