I can't helping thinking "right problem, wrong solution". I would take the bet that there's more ongoing demand for voice calls than many in the tech community realize -- but I don't think this demand is primarily among close-knit teams. Our team used Hipchat for a while, which was notable because it had a button for 1-click voice or video calls... a button no one ever clicked.
