Dear customer..here is the solution

Sometimes when you put a new (or alternate) voicemail system on a Norstar switch, The feature codes that accessed the old system stay in the KSU memory. If this is the case all of your feature codes will appear inactive even if the voicemail system is operating correctly.
To fix this issue you need to run an External Feature test (XFtest) to identify and remove the leftover codes from your KSU memory. You must have a programming set to access this menu (M7310, M7324, T7316).
Power down the Voicemail unit. Remove connection to voicemail ports from KSU.
1. Press [Feature] **938378 (XFtest). The password will be 266344 (Config).
2. Your display will read Feat code: and you will have options First and Exit.
3. Press First. The first stored feature code will appear, and you will have options Test, Back, and Next.
4. Press Test. Your options will read Remove and OK. Press Remove.
5. Once the feature code is removed, press Next to go to the next code.
6. Do this with all codes until your display reads None Registered
7. Release
Restore connections to the voicemail ports from the KSU. Power the system back up.
The feature codes will be restored to the correct defaults with the completion of the voicemail power-up cycle.

thank u

Is the phone system working but the voicemail did not come back up ? Can you tell me what kind of voicemail you have, ist should be marked on the voicemail system ?

SOURCE: Programming feature access keys

These Keys may be set as line keys instead of feature access or not tagged as "feature access" in the programming, also you can only have so many feature access keys... 8 comes to mind but I could be wrong, some features can be programmed permanently onto a button in the main programming so you can free up some more feature access (user programable) buttons.
