Can someone dumb this down for me? It took one month (no exaggeration) for Ooma to respond to my e-mail inquiries. I have some other questions, but have read about their lousy customer service.

I'm interested in Ooma, but am fuzzy on some things:

- I have two lines into my home (I work from home). If I want to use the existing phones for my residential line (two of them) and my single business phone, do I need to purchase two units?

- Besides the taxes and a slicker look, what is the difference between the Core and the Telo

- Is anyone nervous about how three Ooma executives being either fired or replaced this year?
