Feature 983
password is: 1020000 (if you use 3 difit extensions)
OR
120000 (if you have 2 digit extensions)

Actually, even as a technician, you will never know the origonal password.
But you can get in to reset the existing password back to 0 0 0 0.

There are a couple of steps; depending on your voicemail system, voicemail's are done differently, but try this first.

got to a M7310 set
-> dial FEATURE 9 8 3
-> password: 1 0 2 0 0 0 0
-> you should now see ADMIN and under that MBOX, AA, OTHR
press MBOX
-> press CHNG
-> dial the extension of the phones that you need changed
-> you should now see PASSWORD and under it RESET, press RESET (This resets the mailbox back to 4- zero's)
-> hit the * to back up and repeat fopr all the other extensions.
-> hit RLS after all is done and voila... you have now changed those passwords to those mailboxes.

Now when the new users dial F981 at their desks, and dial 0 0 0 0 the first prompt they get is pleasde change password.
