The reason for asking calls to be blocked is important here.

Yes, it would be good if something happens when you receive unwanted
communication attempts.

When it is purely about configuring authorization policies then the
following mechanism might be more appropriate:
http://tools.ietf.org/html/draft-tschofenig-sipping-spit-policy-01

It re-uses mechanisms we have specified already elsewhere and can be outside
a specific call establishment procedure (which is reasonable also in the
on-vaction example you mentioned). 

A more sensible approach of handling my calls to you when you are on vaction
is to forward my calls to your mailbox rather than blocking them and
dropping them on the floor. Sure, it is your policy what todo with my calls
but ... 

One of the mentioned examples, namely telemarketing, lead me to believe that
this is not about configuring my buddy lists.
