I can't figure out how to do this. The Unity Connection 8.x article mentions:
Caller input settings define actions that Cisco Unity Connection takes in response to phone keys pressed by callers during a call handler greeting. By using the settings on the Edit Greeting page for each individual greeting, you can specify on a per-greeting basis whether the greeting allows caller input and whether callers can perform transfers. Or, you can define caller input keys and options that apply to all of the call handler greetings by using the Caller Input page for the call handler.
However when I go into each greeting and change it, it modifies it for all greetings. I'm trying to modify an old call handler that I imported from 4.x that looks like it was setup this way in 4.x. Is this feature gone?
