How about adding items like:
Find a subject matter expert with a single call or click with Expert Advisor (part of Contact Center Enterprise)
Cisco's Speech Connect application
User Voice Recognition login to IP Phones (with 3rd Party app).
Here are a couple of other things:
Problably the coolest thing is TelePresence, if I judge on the impact it has when shown to customers. It's really love at first sight, particularly when they are asked to start the call and manipulate the IP Phone without any previous training.
Now, more down to earth, and again looking from a customer perspective, a very nice thing is Single Number Reach. I know it's probably not so fancy to some of us who are used to play with the very latest Cisco products and features, but when you show to customers that they only need one number and that they can really send the call back and forwards from the IP Phone to any device, they really like it. For me, it's been a tremendous improvement in being reachable to my customers. One number, one way of contacting me.
