Go back to your vendor and get the password for mailbox 999 and the instructions to log into it.

The mailbox exists or it wouldn't ask for a password (they're assigned by default), so you need to go to mailbox 999 and chose option 6 1 3 which is mailbox administration reset password. That will clear the password and you can log into the voice mail automatically from the extension by dialing the voice mail access code.

Post back if you have any problems.

Need to change password on voicemail extension on

If it's a Panasonic brand voice mail, you administer the system from the System Owner's mailbox (999). With that, you can use option 4 or 5 and reset the mailbox password to any and all mailboxes (except 999 :-)

An employee changed the password to the voicemail, and they are no longer with us. How do I override their password and change it back to the default password for the new employee?

Depending on the type of voicemail you have, you''ll have to login to the admin mailbox. That's done by pressing your voicemail key or intercom 777. If you have a Partnermail VS the admin mailbox is 99 with the default password of 1234. If you mave a Partner Messaging System the admin mailbox is 0 with a default password of 1234 or 123456. Once your into the admin mailbox press 9 for admin programming. ,(depending on version) press either 2 or 4 administer extensions, enter the mailbox number of the box you want to reset, press 3 to re initalize the password, hang up when done

M7310: Phone number

Sorry about the delay, I lost your post and could not get back in touch with you... This is a case where a certified Norstar tech will come in handy...
OK - lets get started.... Do you have the programming password to get into the system? Do you have the programming template (piece of paper to guide you thru the proper steps in which button to press?)
If you do lets go: Go to a set, hopefully a bigger set with 2 rows of buttons... -> Feature * * 2 6 6 3 4 4 -> is this is a CIC's/MIC's system it will ask for a password see next step, if this is a BCM it will ask you for a User ID:___ your default ID is 738662 -> Password:___ default is 266344
-> now you will see TERMINALS&SETS... keep hitting the NEXT button off the template till you see SYSTEM PRGRMING... -> now hit the ENTER and press the NEXT key till you see CHANGE DN -> now press ENTER this is were you will type in the old extension number (EX:2331) then type in the new extension number that you want the set to have (EX:5331) -> now hit the RLS button... check to see if the number changed but pressing FEATURE * 0 and pressing the INTERCOM key.
Now there are a few things that you have to remember, the voicemail has not been changed, the new extension needs to be programmed into the TARGETLINE for your DID number to ring at your desk, and if you have your extension as a Busy Lamp Field on the front reception, you have to change that to your new extension by going to the receptionist desk: ->FEATURE * 2, pressing your button, and dialing your new extension. -> now to see what your direct number target line is, press FEATURE * ) and press the button for your direct line... and see what LINE number you have, now get back into the system programming and find LINES and type in the number that you found on your phone (EX:255), press ENTER and press ENTER again you should see TARGET LINE. -> Keep pressing NEXT till you seePRIMESET:___ this has your old extension and press CHANGE and type in your new extension. -> hit the NEXT button and RLS -> your voicemail dial FEATURE 9 8 3 If you have a BCM your default LOG:___ is 738662 but if you have a MIC/CIC's system it will say password: default password is 10020000 for a 4 digit extension, 1020000 for a 3 digit extension. But if this a BCM the default password will be 2 6 6 3 4 4 -> press MBOX -> press CHNG -> your old extension -> you should now see PASSWORD press NEXT and you should see your old extension press CHNG and type in your new extension. Hit the next button after inputting this information, until you get back to the MAILBOX ADMIN and hit RLS.

Voila you are done! Good Luck

How do you change passwords without knowing previous passwords in order to change voicemail greeting??

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.

How to set up password for voicemail/how to set up new mailbox

By default, a Panasonic TVA voice mail system can have a password set. It could be 3 plus the extension number, but it doesn't matter. You can clear it by logging into mailbox 999 and going to options 6 1 3 which will be the mailbox password menu. Select the lady's extension and follow the instructions to confirm password deletion.

Now she can call voice mail from her extension and set a new password.

This also works for a TVS system.

How do I change the voice mail recorded message? How do I get a manual for this existing system?

IF you know the password for the mailbox then log into the voicemail by dialing the Stratagy access code, after Stratagy answers dial * , then your user ID mailbox number plus #, then your security code plus #. The User Main Menu plays, press 2 to change your greeting, the Select Greeting Menu plays, press the greeting number, the Record Menu plays, press 2 to record your greeting, Record greeting, as soon as you finish press #, the Record Greeting Menu plays, press 1 to review or 2 to re-record.

From an admin phone, enter the voicemail. Then select More, Mgr, ChBox, then enter the ext# you need to reset the password on. Then choose Reset Password (Select Yes when the system asks you if want to reset the password). You can access the reset extension's voicemail by entering the default code.
