Hi Inaki
You could include the presence of a SIP endpoint (your phone) as another 
resource into your XMPP state. If one of your SIP phones is in a call, the XMPP 
resource will be e.g. busy.

If you "set DND on the SIP phone", it could be easily mapped to a XMPP state, 
i.e. somehow trigger the resource to become busy as well.

I think also integration at this level is something worth to consider. Not 
"SIMPLE users interact with XMPP users" but to let each protocol do what its 
good at (chat through XMPP and call through SIP). I have not met too many 
SIMPLE users to chat with yet anyways :) The user could have a single URI and 
there would be no confusion.
