Voice: CSS on MWI numbers ?

Hi,
I've always thought of CSS as "what you see" of the dialplan,
and partitions as "where are you", sort of.

Partitions are, mathematicaly speaking, partitions. :)
I.e., a DN only belongs to one.
CSSs are ordered lists of partitions "visible" to a call originator.

If I'm ok so far, what's the point in having CSS assigned to a MWI
DN ? AFAIK, this is not going to originate a call ever.

Enlightment is welcome,
-Carlos
