This may also be a topic for Unity Express--
Is there a USER GUI to change call-forwarding settings? As administrator, I can do it using the CLI, the CCME GUI, or the Unity Express GUI. As a normal user, however, neither GUI offers that option. [I have no intention of offering CLI to users :) ] Am I missing something, or is that just the way it is?
As an aside, this particular system will also make heavy use of extension mobility, and I just learned that v4.2(1) will at least allow users to have speed dials. Up until today, I thought that was a goner too, since I was running v4.2 and could find no way to do this either.
