I'm using an separate autoattendant which has a small delay before completing a transfer. This is a problem when phones are busy or fwd all to Unity. Callers don't hear the first couple of seconds of a greeting.
There is an advanced setting for delay before prompt but it interferes whith the "blank greeting" setting -actually putting the delay before all greetings including blank.
I just need Unity to answer after 2-3 seconds - not immediately.
