In our July/August issue, we wrote about the latest version of Ooma's highly-rated VoIP phone system. Launched a couple years ago, Ooma's system allows you to make free domestic calls, and call internationally for as little as 1.4 cents per minute. The upgraded version, called the Telo, comes with a handset and some added features, but the older model is on sale at Dell for just $172, compared with $300 and up for the Telo.
