I want to wipe out all programming on a nortelflashtalk voicemail

You would need to log in as the voicemail admin using "Feature 983" followed by 102 (if you have 3 digit extension numbers) then the voicemail admin password. From there you can select MBOX and reset the password to 0000 for the mailbox in question.

"Q: My Norstar Startalk, Flashtalk, or voice mail says my mailbox is not accepting any more messages. I deleted all my messages, but callers still cannot leave a message. Why?
A: Check with your voice mail administrator. Chances are another Mailbox on the system used up all the message storage space. Usually it's the general delivery mailbox that hasn't been checked for messages on a regular basis."

If none of your voicemail feature codes(f980-f989) are active, then that means that the system doesn't recognize any nortel voicemail on the system.Which means that a) your system has a non-nortel voicemail system attached to it, b) theres no voicemail attached to the system at all or c) the voicemail is no longer functioning.

If you are asking how to setup the voicemail system, the best thing to do is to hire a technician familiar with all the installation & programming procedures. Hope this helps.

I dial my number and press ** when the VM picks up, then it should run you through the regular login process.

dial your voicemail, put in your password, after you are in the voicemail, press 8 and listen to the prompts, it will tell you were to record your name for the company directory.

Cycle the power on the voicemail system. If that does not work, you may have to replace the voicemail power supply, or send the voicemail system for repair.
Good Luck!

Have you set up the voicemail before?

OK, from your set;
-> dial FEATURE 9 8 1 (this is the code to get you to the voicemail)
-> then your passcode, if you never set up the voicemail, the temporary password is 0 0 0 0 (four - zero's).
-> if this is a new installed voicemail, the telephone system will tell you al that you need to initiate the voicemail box.

This is the forums for Avaya, I would repost in the Nortel side. BUT, i do know the CICS needs to be of the correct revision to work with CP.

The mailboxes don't need to have saved messages, to be full. More then likely what is happening is that when people call in, they are getting a generic/Auto Attendant vm box, and that one is full. Try checking vm box #100, or #10. That is the Nortel standard general delivery vm box. Please let me know is this helps, or if you more help.
