Nortel T7316E. Trying to unlock a mailbox. I know how to do this, however when I press function 983, the voice says 'you do not have access to this function'. What can I do to get access??

I will share how I've learned and "that's the hard way". In your search engine, type in programming for notel meridian 7310 and you will find several that provide comprehensive programming.

In the notes I have printed, to log into System Administration,
Enter Feature 983 (the display will show "LOG" and then enter your password.

Your password depends on the number of digits for each extension number:
If your company extensions are 2 digits long enter "120000"
If your company extensions are 3 digits long enter: 1020000"
If you company extensions are 4 digits long enter: "10020000"

Another useful feature is FEATURE **23646 AND THE PASSWORD IS 23646, all you need to do is follow the overlay prompts.
