Our organization is thinking of upgrading our traditional voice only calls and conferences, I use Skype and Google hangouts for personal use, but I don't think they appropriate in a business setting. I know they are great for chatting with friends or family, but they often lack the security, reliability and performance of enterprise-grade video solutions. We are thinking of upgrading to a web or video conferencing technology. Are video and web conferencing expensive? What are the most reliable web and video conferencing in the market today?
