You didn't quite give enough info in your question for me
to give a definitive answer, but ... in most cellco and many
landline v-mail systems, there's a quasi "backdoor" method
to get to your msgs.
This is so that you can gain access if you're away from your
phone.
In Omnipoint's system, for example, you call the
v-mail entry point at 305-MESSAGE. You then enter
in the phone number whose messages you're checking,
and... and then you have to enter in a password (numeric)
that you've pre-chosen.
your physical phone never rings.
You can check your msgs and also listen to/change
your outgoing msg.
Now.. there is a very, very, annoying and disturbing
security breach on most of these systems.
If you're calling from your own phone to check v-mail,
typically there's a shortcut number _and_ you do NOT
have to enter in a password. The system "recognizes"
(kind of - see below) that you're reaching it from
the owner's phone and thus figures you're entitled
to hear them.
THe problem: Far too many of these systems use "caller id"
to verify who you are. And (not to get too techy about it),
it's pretty trivial for "bad guys" to spoof caller id.
In other words, that number you see "calling you" on your
little screen may, or may not... be the real number
trying to get you. Same for the v-mail system... a Bad Guy
can fake your number.. and that will give him direct access
to your v-mail w/o a password of other real check.
