I have a mailbox I am trying to set up on a Norstar T7316E, but it won't give me the option of choosing a subscription mailbox; it automatically defaults to information, and it doesn't give me the option of changing it. I need this particular mailbox to have the ability of accepting voicemails, how do I fix this?

You will need to dial into the system admin of the voicemail
Feature 983
the password is dependant on how many digits your extensions use. 1020000 for 3 digit and 10020000 for 4 digit, 120000 for 2 digit.
go through the screens

Mailboxes, modify, scroll to password and press change.
Will reset to 0000.

This generally happens from one of two things. Your voice mail system is connected to your phone system through a station port. If it loses connection it will not communicate with the phone system. Loose wire or connection can cause this. or it has just crashed and will need repair or replacement.

First thing you want to do is unplug the unit wait 15 minutes and plug it back in. wait 10 minutes Try feature 981 from a set that has voicemail. if nothing. hit feature 985 from a m7310 set or a m7324 set not a m7208. If it comes back with inactive fearture now your connection between the units is bad or the unit itself is bad. If it comes back with the voicemail intercom # and you cant get into any mailboxes it has lost all programming.Try this first.

Ok, do you know how to get into system programming?

If you do:
-> first dial FEATURE 985 this will give you the DN(Extn) for the voicemail
-> get into programming
-> TERMINALS&SETS enter and put in the extn that is giving you issues
-> then under CAPABILITIES look for FWD NO ANSWER and put in the DN of the voicemail you saw with the Feature 985
-> hit next for the number of rings you want it to ring before going to voicemail
-> hit next and you can now RLS to back out of programming.

Voila, that set will now goto voicemail.
