It is ANI (annie) and ANI II (Annie Eye Eye) not ANI 2. Also, not everyone calls it "Annie". I've had some debate with other phreaks about this in the past. Strom and I still can't decide who is right on this subject. When I worked for phone companies we called it "Annie" but it seems other phreaks and some telcos just call it A-N-I. This was also part of our debate on "telephony" being "Tel-eff-in-ee" or "Tel-uh-phony".
Hah, you beat me to it! Yes, Annie Two sounds like a sequel to an overused movie title. I've never heard The Phone Company talk about II digits, but II digits are referred to in documents as "information integers". Officially, I've heard ANI pronounced as Annie. That being said, though, I think there's a bit of a mystery regarding how transmitted digits can end up being displayed to the distant equipment. For example, an ANI fail via the operator will show up at the distant end as 23 very often, but a more formal ANI fail from an exchange not programmed to send ANI for whatever reason will show up as something other than 02 even if the switch specifically sends that out - I think just 00.
None of this actually applies to attempts at an ANI fail from most voice over IP providers to the best of my knowledge. The reason being that if you assign no number to your call, a media gateway will often give you a generic number. Alternatively, if someone tries to assign 000-000-0000 to a call, it's literally 000-000-0000 instead of a fail (which sends nothing, or just area code). Though some ANACs will read a fail back as all zeroes, it'll do this simply because it's programmed to read back ten digits, but there's no digits to read. The reality is it still shows up in logs as 000-000-0000 if that's what you assign the number as. In a nutshell, it sounds as authentic as walking into a Mexican restaurant and ordering a crunchy taco supreme; you're distinguishing your call from other ANI fails, and someone - or something is likely to use that to identify you.
How would I find these ANI, and ANI 2 numbers other than just guessing?
I'd check blocks of numbers owned by IVR companies, such as West Interactive or First Data Voice Services. They're probably going to be the biggest users of them, and have enough resources at their disposal to construct it on a whim. Aside from checking local ranges they own, tollfreeda.com or 800-555-1212 have gotten lucky occasionally, and inadvertently listed test lines. That would be the first place I'd look.
In any event, we really do need a new II digit ANAC, though, maybe this should be an organized effort.
In the mid 2000s manually op diverting started to get pretty hard, and when you could pull it off they would generally forward your ANI. The way me and my friends got around this took a lot of work.
Maybe it's just a thing native to your telco, but I've never run into any trouble op diverting.
