Yes, method confirmed. Thank you! (P.S:  Don't give out invites to people that request them online.)

800-444-4444 belongs to MCI and I suppose they might some day get tired of people using it for this purpose, rather than what they intended, which is for their customers to call them about their accounts.

This method does not seem to work on Verizon Wireless.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! all3ykat 1/16/10 9:32 PM
I use Verizon and I tried this method three days ago and it worked perfectly.  MCI's number was reading back a three digit number that I was calling from, something like 527.  Now MCI's 1-800-444-4444 number reads back my GV ANI.  This is no longer functionable for whatever reason.  Fscking blows.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! Skunkworks 1/24/10 2:44 PM

Ok well things have changed a bit. This still does work, but the ANI and CPN are no longer 404-260-5532.
 
Google voice is now causing something known as an ANI failure when you place a call after dialing in with *67 caller ID blocking.
 
The new data being passed is as follows:
ANI: 585 (ANI Failure)
Caller ID: Private
CPN: 585+Privacy Bit
ANI-II: 00 (POTS/Landline)
 
This doesn't have much effect on my privacy trick, it will still work fine!
 
The only difference is that the call now appears to be "operator assisted," and a few toll free numbers will automatically reject the call.
 
To everyone who isn't getting the trick to work: are you sure your doing the following steps?
1. dial *67 (won't work if you skip this, this trick won't work with web initiated calls!)
2. dial google voice number
3. dial * and then your pin unless you are calling from one of your forwarding phones
4. dial 2 and then dial the number you want to call followed by #

@ebear422
Very true, although wikipedia's artile on ANACs (phone numbers that read back your phone number) mentions the 800-444-4444 ANAC, so it's no huge secret. (see http://en.wikipedia.org/wiki/Automatic_number_announcement_circuit)

@all3ykat
You were trying right when it switched over from 404-260-5532 to 585, so I'd try again now and report back

Not a google voice solution, but my favorite way to call an 800 number is from a payphone, those disappearing thingamajigs!  You don't have to put coins in to call a toll free number, if you can find a workjing payphone.

I used to work for the IRS. People are terrified of the IRS, and I won't elaborate here.  The IRS usually won't track your calls, unless they think you are suicidal over a tax bill, etc.  Then they have some emergency ways of finding you to save your life.

If you really fear someone like the IRS, go to a payphone and call. the toll-free number.  Don't identify yourself.  Say, what if someone owes you X amount of dollars, no longer has the high paying job from the last 2 years, and what will happen if the person can't pay?

Just describe your situation anonymously as well as you can. You should be able to get details of stuff like payment plans or whether or not they will put you into a "currently not collectible status."  They have to explain the options.

Then, when you feel comfortable, contact them and identify yourself.

This advice works for just about anybody you owe:  call anonymously and get general info first.

I'm not afraid of my credit card collectors, but I don't want them calling me at home, and am looking intently at google voice and its number cloaking mechanisms.

Now, at my classic home phone, I am getting too many other people's collectors as well as my own.  My mother, who has no bills, is also getting calls over at least 3 other people's bills.

I supposed the collectors are really greedy and desparate these days.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! Skunkworks 1/26/10 4:55 PM
Update: MCI refuses to connect calls to their 800-444-4444 ANAC when the call has ANI failure. The number will ringout before going to a reorder when you call with this "cloaking technique."
 
Also it appears that the other ANAC I listed (888-253-8239) has now been assigned to a company (maybe they found this thread and thought it was a way to get some extra calls? haha)
 
Another inactive toll free number that will function the same way is 888-776-5733. It will say the realtime ANI was not transmitted when you use my anonymity trick.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! Skunkworks 2/18/10 1:25 PM
UPDATE:
 
THIS TRICK NO LONGER WORKS AS OF TWO DAYS AGO
 
Google voice has stopped handling privacy bits properly, so whether you dial *67 before calling your google voice number to dial out or not, your outbound CPN, Caller ID and ANI will all now display your real google voice number!
 
Obviously this makes just blocking your Caller ID over google voice impossible, which is obviously a major setback in privacy! Hopefully this will be fixed soon. I'll reply back to this thread if and when it is. I encourage you to submit a trouble ticket to google about not being able to block your Caller ID anymore if this continues for more than a few days.

^^ yup hes right it no longers works!

Thank you Skunkworks for your knowledge and for sharing this knowledge on this forum.  It seems you have researched other ways after MCI's number stopped working and they were effective for a short while but no longer are.  I respect and appreciate this.  Thanks man.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! tatiami 3/5/10 11:05 AM
Thank Skunkworks. You're absolutely right. Regardless your phone number is block or not blocking, when making a call thru GV, it shows the GV number. GV need to fix this problem.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! z32tt 4/10/10 12:36 PM
I don't this is a "actual" problem GV has!lol @ previous comment. Any new tricks related to this?
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! Makapav 5/6/10 9:09 PM
I have a slightly different but maybe related problem with using GV to call Lenovo toll free numbers. I was directed to this thread from my original post here:


Contents of the original post:

I have been using google voice for a while with my Android phone. Although I have gv toggle set to 'ask every time' 99% of all calls are made through gv except when I don't have internet connection for it to work.

Lately, I noticed that when I dial Lenovo's toll-free numbers (e.g. 1-866-968-4465) the receiving part never picks up and the ringing goes on forever until disconnect. However, when I call directly without gv or through a regular phone line the call connects.

This sounds like a codec/protocol mismatch issue.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! airbournone 5/28/10 9:24 AM
My experience dialing 800 numbers with GV accords with Makapav's post above- often rings with no answer and an eventual disconnection.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! trots 6/12/10 3:49 PM
As far as I know the vast majority of toll free numbers (or any phone number attached to a call center or computerized system)  get CPN data, not old fashioned "Real" ANI or BTN or anything like that anymore.  Anyway, with VoIP it's real easy to spoof your number to tollfree numbers.  Several carriers maintain open toll free gateways.  For example: tf.callwithus.com and proxy01.sipphone.com .  In your softphone or ATA, whatever 10 digit number you put into the userid field will become your CPN.  This means you probably don't want to mess up an active ata, so it is best to try it on a spare softphone.  Now call 1 800 444 4444  or via sip that is 18004444444(at)proxy01.sipphone.com .  Note that some softphones are somewhat crippled and do not allow dialing via sip uri.  Whatever your using for the userid is read back by MCI's system.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! Skunkworks 6/26/10 12:44 PM
Appears GV is once again producing similar results as from my initial post (meaning it is again possible to call toll-free numbers anonymously using GV)

The three digit ANI+CPN now seems to vary though, I've heard both 804 and 617 thus far.

@trots
interesting info!

Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! smbyers 10/2/10 6:55 PM
I've dialed *67, my GV #, option 2, and then the # I want to call and it comes accros as unknown name/unknown number on caller ID.
Re: HOWTO: Call Toll-Free Numbers Anonymously with Google Voice! GW 2/4/11 8:37 AM
The *67 doesn't appear to be working now. However, if you are using GV from your cellphone that's a forwarding number on your account and dialing with the Google Voice app, you can block your caller ID. If your phone is set to hide your number, GV follows suit. I just tested this by calling my husband and he said the caller ID came up as "Unknown".
