Hi,
It sounds like you may be observing a known issue, CSCsg36208:
Symptom:
Under the greetings settings for a Call Handler's Standard greeting, Status
is set to 'Disabled' and is greyed out preventing change. The Standard
Greeting still functions normally.
Conditions:
Reported on a customer system running Cisco Unity 4.2(1). New install.
Workaround:
To correct this status displayed in the SA and/or if the Standard Greeting
truly is disabled then latest version of DBWalker run without any options
selected will correct this. It will display the following message:
Greeting rule Standard
1195:(error) Standard messaging rule was disabled, which should never be
possible.
1253:(fixed) Standard messaging rule automatically enabled.
If running DBWalker does not correct the problem contact TAC for further
assistance.
NOTE: The Standard Greeting is designed such that it can never be disabled,
it plays all the time unless overridden by another greeting.
I hope this helps.
