I'm surprised how many people (maybe it's just my age group) don't know about Gmail's North America's free voice calling feature. I've been using it for a couple of years now and every December they seem to extend the free calling period-actually I'm sure it's always going to be free, it's just an excuse to advertise it by extending it every year. I use it regularly and while the line isn't always clear, I'd say it registers as good or better at about 70% of the time and really is an excellent alternative to long distance charges. I usually use it when I am calling a number where I know I'm going to be on hold a while. It frees up your land line or cell for incoming calls during that waiting period.
Of course, you need a GMail account to make it work but I personally believe GMail is the best web based mail out there so if you don't already have it, this feature alone makes it worth trying out.
Get it from Google
