VT Advantage is basically your only option if you want to provide video 
from the desktop IP phone.  If you want room-based solutions they can 
integrate with CallManager in multiple ways (as mentioned in previous 
emails) but they are going to be dedicated units in a room (or on a 
crash cart, etc.)

As far as providing overflow from IP to ISDN, I can't even think how to 
do that.  The biggest thing standing in the way is that you would need 
to change the destination being dialed from an IP address to a phone 
number :-\
