I like the features listed above.

Another feature I'd like to see is one I had with my last provider, a DND scheduler by day of week and time. I liked setting it up so as to not get calls late or in the middle of the night unless they were on my whitelist, with a message indicating I'm not accepting calls right now and to try back later as opposed to the busy signal or voicemail option now with no scheduler. Just my 2 cents.
