So do I understand correctly that during the course of a single call the 
Called Party ID can change multiple times, and be reflected on the phone's 
display (ala SIP update)?

If so that's fantastic news.  ZipDX the conference calling company does 
something similar to convey status updates to the endpoints of the 
sip-connected conference members.  It's an excellent use of technology. 
Your app_voicemail example is apropos.  I've always thought it would be 
efficient to use SIP update to have app_voicemail send message duration, 
name info etc to the endpoint display.
