Voice over Internet Protocol (VOIP) is definitely here to stay. If you haven't checked into it yet for your company, you should. It could possibly save you a ton of money. The quality is generally excellent now, and this is not your old voip in the beginning where the call quality was marginal at best. This is now a very mature product, and in fact, the long distance companies have been doing it behind the scenes for a long time. If you ever made a long distance phone call, odds are some part of the call was run over voip, with or without your knowledge.
