I had my home landline ported to Ooma two weeks ago. So far I haven't noticed any difference. I split the line (with the standard splitter that came with the Ooma) and plug it into a four handset base station and to my DishNetwork DVR. The DVR is happy and the phone works fine. I have read that some people have had issues setting up the DVR correctly, but mine just worked.
I will probably end up paying the $60 additional for a year of premium service (normally $100, but I already paid $40 to port my number, which they will apply to the first year of premium) because some of the features are interesting enough to justify trying them out for $5 per month for a year.
