With two very limited exceptions FCC regulations require that
SS7-capable carriers honor *67. This is set forth in 47 Code of Federal
Regulation 64.1601, of which I cite the pertinent language:
-------------------------------------------------------------------------
47 CFR 64.1601:
(b) Privacy. Except as provided in paragraph (d) of this section,
originating carriers using Signaling System 7 and offering or
subscribing to any service based on Signaling System 7 functionality
will recognize *67 dialed as the first three digits of a call (or 1167
for rotary or pulse dialing phones) as a caller�s request that the CPN
not be passed on an interstate call. Such carriers providing line
blocking services will recognize *82 as a caller�s request that the CPN
be passed on an interstate call. No common carrier sub-scribing to or
offering any service that delivers CPN may override the privacy
indicator associated with an interstate call. Carriers must arrange
their CPN- based services, and billing practices, in such a manner that
when a caller requests that the CPN not be passed, a carrier may not
reveal that caller�s number or name, nor may the carrier use the number
or name to allow the called party to contact the calling party. The
terminating carrier must act in accordance with the privacy indicator
unless the call is made to a called party that subscribes to an ANI or
charge number based service and the call is paid for by the called party.
(d) Exemptions. Section 64.1601(a) and (b) shall not apply when: (1) A
call originates from a payphone. (2) A local exchange carrier with
Signaling System 7 capability does not have the software to provide *67
or *82 functionalities. Such carriers are prohibited from passing CPN.

Here is what the Vonage web site says about per-call block:
"Caller ID Block protects your privacy when making a call.
Caller ID Block
Don't want the person you're calling to know your number? Block it! You
can turn on Caller ID Block when you pick up the phone to make the call.
So go ahead, call from home. Caller ID Block will protect your privacy,
giving you the freedom to call anybody you want.
How to Use Caller ID Block
Turn on Caller ID Block in an instant! Just dial *67 before you dial the
number. Caller ID Block turns off automatically when you hang up."
-------------------------------------------------------------------------
I have attempted for many months (probably over one year) to get Vonage
to make the feature work. I even told them it�s required by FCC
regulation on inter-state calls. Sigh, they do nothing.
I have filed two informal complaints with the FAA, both of which have
been summarily dismissed and cite lack of jurisdiction. In the second
complaint I cited 47 CFR 64.1601, which was simply ignored in the
dismissal. The FCC refers me to the California PUC, even though my
complaint states that the problem occurs on interstate calls.
Anyone here have any thoughts, comments, or ideas?

[FCC regs snipped. thanks for posting them]
FYI, T-Mobile offers a pseudo VOIP "landline" service where they
provide you with a SIM _and_ a t-Mobile "branded" internet
router. When you hook the router to an internet feed, you
can plug a traditional wired phone (or answering machine, etc.
[but not fax...]) into the RJ-11 jacks on the back and
get, just like with Vonage, etc., what looks and acts like
a traditional wireline phone. (Yes, we all know the differnces).
I tried using "*67" when making an outgoing call and it
didn't work. I punched the code in and waited, and a second
or so later, instead of the "stutter", I got a rapid busy
(as in "no good") noise.
I was "this close" to getting super pissed when, for some
reason or another, I tried just quickly punching in all
the digits (that is, *67-xxx-xxx-nnnn) without pausing
after the code. And it worked.
Ain't nothing anywhere in the t-Mobile info about it.
Anyway, just mentioning this for what it's worth.
(disclosure: I'm a user and a shareholder).

I don't understand why they can't block caller-ID.
In my humble opinion (IMHO), many of the VOIP providers are able to
discount their services because they take shortcuts with the results
as you describe.
However, call-block is a dubious feature. My cell phone came with it
as the default setting and I found it necessary to have them disable
it. Almost everyone I call won't accept blocked calls.
I don't see that exception in the FCC regulation. ;-)

I seldom have a need to use it, but when I do I expect it to work as the
law requires.

Then again, *67 and *82 are mandated by the FCC to be free of all charges.
