We did port our land line number over to Ooma which wasn't cheap (i.e., $45.59), but it's a one time cost and we factored it into the break even point

I was able to port my land line number effortlessly

Also keeping my old land line number is a plus so I can separate who calls my cell number so I don't get annoyed by call vendors.

I use a land line number for everything I buy so its the number many telemarketers get their hands on instead of my cell

I got Ooma premier service with a Linx box for a separate line/number in my home office.

Voice quality is excellent; other end doesn't even suspect I

well i really like the 5$ phone bill ease of use ? took 7 days to port the number at a cost of 47$ all these added costs are not to my liking
