More than 5 MyFaves

I recently ran across a couple of companies that effectively make it possible to provide you with more than 5 MyFaves. One of these that I just saw is RingBranch at www.ringbranch.com I am using RingBranch and am able to add the number that they give me as one of my 5 MyFaves. So, when I call that number, I can then connect to any of the people in my contact list and don't have to use plan minutes. Their blog provides more info at http://ringbranch.typepad.com/ringbra...

Has anyone used this or other services like it that make this possible?
