This is a deal I can recommend 100%.  Since we switched to Ooma in March of 2016 we’ve saved $1,051 (so it tells me on the dashboard).  Block as many calls as you want using several options – – I’ll go days without a garbage call!  Pay only taxes each month for the plain vanilla plan or upgrade to premium like I did (it included the port fee) and pay an annual fee plus the taxes.  Lots more features with premium and still a fraction of what I was paying Ma Bell for much higher quality sound and features I actually use.  Port your current number over and unplug from the landline and you’ll be glad you did.
