I routinely leave backdoor voicemail for
Cingular subscribers in Bay Area area
codes 415, 510, 650, 408, 707, and 925.

In the past, for any particular Bay Area
Cingular voicemail subscriber, one of
these access numbers always allowed me
to leave a backdoor voicemail:

  510-333-1234
  707-301-0008
  408-250-1234

(There's not much correlation between
the subscriber's Cingular area code and
the area code of the backdoor that
works for their account.)

Now I've run into a 510 Cingular
voicemail subscriber for whom I'm unable
so far to find a working backdoor.  Two
possibilities occur to me:

(1) For newer Cingular subscribers,
voicemail backdoors don't exist.

(2) There is a new Cingular Bay Area
voicemail platform for which I don't
yet have a backdoor number.

So I turn to you for help.  Can you
locate a back door for 510-331-7321?
(You'll know that you've succeeded
when the system replies with "Please
hold; your call is being transferred."
You should hang up at that point.)

(PLEASE NOTE: 510-331-7321 belongs to
a stranger, so please (a) don't call
the number and (b) don't leave a
a backdoor message for it.  I post
this message not for the purpose
of communicating with that stranger,
but rather in the interest having a
functionally complete list of Bay Area
Cingular voicemail backdoor numbers.)
