There are I believe legal requirements (at least in some countries)  
that require you to inform users that the call may be recorded and
used for quality control or training purposes etc.

I can envisage voice services tied to a web site where you can view
their privacy policy and set your preferences etc. When you dial
into the voice service, the web site would be able to identify you
in one of several ways, and to apply your preferences accordingly.

A further idea is the ability to combine P3P with SIP when the
voice call is set up via SIP. SIP (session initiation protocol)
is similar to HTTP in the way it uses headers, and is expected
to play an increasingly important role as time goes by.
