Panasonic Kx-dt343, Password Lost. Tried 998# & 999# Without Success.

It depends on what you mean by "can't access". The Panasonic voice mail system is accessed by dialing the VM access code, sometimes 500 or 165, from the phone you want to use. If you, for example, are extension 105, and it has a voice mail box, the lady will either tell you how many messages you have, or ask for a password. If that's how you can't access VM because you don't have a password, then the password can be reset from mailbox 999, the system administrator's mailbox.

There are two passwords YOU ABSOLUTELY HAVE TO HAVE. If you don't know the passwords to 998 and 999, then you will have to get them from the original installer, or call your Panasonic dealer. Alternatively, if you have the VM maintenance console password, you can reset 998 and 999's password.

I hope this is helpful to you!
