I you want in integrated view of all calls and not just the ones for  
which the INVITEs reached a particular device.
For example, I have serial forking which rings my desk phone and only  
if it doesn't answer does it ring my cell phone. I would however,  
like a full view of the call log for my AoR, including those that  
never rang anywhere (were screened, went to call coverage because my  
phone was off or disconnected, were answered on one phone but I'd  
like to have the call record on another phone so I can easily  
originate a call from there, etc., etc., etc., etc., etc.)
> Commercial P2P products (Skype) and P2P SIP have no servers...
Henry, I love you, but that's nonsense. Of course they do, for  
voicemail, skypeout, and likely tons of other things. As with most  
things the purist model of no servers at all is the enemy of the  
sweet-spot model which avoids gratuitous use of servers when they add  
no value, introduce scalability and security problems, and just get  
in the way.

> What may the P2P SIP view be for these functions?
Perhaps a fully-replicated distributed database among the Contacts  
for a particular AOR. Of course even if you have that you need a data  
schema, which is mostly what this draft seems to be about.
