Skype gets a lot of deserved publicity for being the clear front-runner with free VOIP services. But is it robust enough for business use? Yes and no. More businesses, especially those with large data networks, are looking at Skype as a Business VOIP alternative. But right now, it's best used as a secondary service, not a primary business phone service. This is because Skype is still basically computer-based software. So for people who sit at the computer all day, it can work. But it won't be so good to handle PBX-style business work. But with calls to other Skype users still free, it can make a great secondary business phone service.
