Cant change time and date on nortel t7208 phone tried the f xx23646 and so on, nothing

It's not so much removing Denied in Admin as it is enabling whatever feature the user was trying to access at that set.
Which was... ?

After entering the mailbox access F981, press "#", the display should change from Pswd: to Log:. Now, enter the alternate mailbox number followed by the password for that box and "#". The remainder of the prompts should be the same as accessing the 'native' mailbox.

You can obtain the manual for this phone at the link below, which may help you reset the password.

Hi....you need to push "feature" button at the top of the phone, then * * 2-3-6-4-6 (a.d.m.i.n ), then when phone asks for password, press 2-3-6-4-6 again, default, unless someone has programmed a different one. use the template link below, this fits over the row of keys on the right side of phone. push "next" until you get to "date and time", and then with a combination of "show" and "change" you can get to change time . try it and see how it goes. email me at [email protected] with questions. link is good for other commands as well. good luck

well you can go to the nortel site where they have an online service where customers can register and get the help needed here is the link http://support.nortel.com/go/main.jsp?cscat=SELFSERVICE

your mailbox number is the last 4 digits of your phone number

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

to change the main greeting you need to get into admin programing F983 your also going to need a 7310 or 7324 or a T7316. You have to use the buttons under the LCD screen to navigate after getting into admin press AA
Press GRTG
Press GRTG again
and usually 1 is set for day
and 2 is set for night
press 1 then ok
Press REC.
Hope this helps
