Groupon offers the Ooma Telo VoIP Phone System, model no. 100-0201-300R, for $49.99 with free shipping, with a required-at-activation Ooma Premier 10-Month Subscription (which will add $9.99 per month). Factoring out the subscription fee, that's $30 under our December mention (which didn't require the Premier subscription) and the best price we've seen for this device purchased new. (It's also a current price low by $60.) It offers unlimited calling to any number in the US via your broadband Internet connection. It features caller ID and a landline backup option.
