Check http://www.phrack.org/phrack/47/P47-15 - I don't know how relevant this is
to the versions that are around today but it may be a starting point. In my
experience it's very common for users to have bad passwords, i.e. the same as
their mailbox number. If you can get into any mailbox this obviously leads to
exposure of voice mails but also potentially to the ability to make outgoing or
internal phone calls, which may be useful for social engineering attacks within
the organisation or making long distance and international calls at the
organisation's expense.
