Yap-Take voicemail to the cloud (and gain analytics)

I'm a busy person.  I volunteer, I consult, and I run a nonprofit.  I don't always have time to answer the phone and when I return phone calls, I like to know how to prioritize.  Yap helps with that.  I've used Google Voice (free numbers are nice), but I wanted to give something else a whirl.  I like that I can text/email the caller back.
