Which VOIP?

sligett thought this was worth mentioning said

Ok, I bought the Ooma thingie for VOIP from Meh, and I plan to set it up over the holiday break. But I see Newegg has a cheap Obihai OBi200 VOIP box today. I've never done a home VOIP thingie. So I'm asking for advice from all the Meh VOIP geeks - will my Ooma do what I need? Is the Obihai better/worse? etc? Will they work in Canada?

Purple?

Thanks.
