I like #19 over #20 but both make little sense. The word "Dial" means phone. The Refractive Dialer logo is a phone's keypad (123,456,789). Your design makes little sense for a phone company.
I still like #10 the best of all of them. You might want to wait another 24 hours or so to see what other designs I like from others so you can improve yours. Just not much to go on right now and I can't offer suggestions since you're design seems just fine right now.
