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
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
. 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
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.
