Sonexis is a company that enables businesses to connect through high quality web and audio conferencing. Founded in 2001, Sonexis is one of the better companies that offer a cheap, and easy to use, web and audio conference system, that does not cost per minute, or as you go, as some other subscription companies do.
Sonexis also provides a few different training courses on how to use their product. Their product, called the Conference Manager, puts the user in complete control, as he or she can decide who can do what, and when. They also offer support and assistance for the Conference Manager in case you run into any problems while using their Conference Manager product.
Another product of similar interest is the video conferencing system, which is starting to surpass the use of traditional web and audio conferencing systems.
