I checked out nettalk.com Looks like they have a number porting option and I wonder if I could port my MJ # to nettalk and then use their CF feature. For me it's not so much a money issue. It's an availability issue and being able to keep my MJ number because it's on my biz cards and I just received a whole new batch of biz cards. It will me take a while to use up my cards. Switching to a service that has CF is cheaper than getting new cards.
