I am searching for a suitable video conference system for our company these days.Our company is going to set up an internet based video conference system. Because we have sub-companies in different places, we need an easy to use, easy to maintain and easy to administer video conference software. I've tried many conference software, but they are not that convenient, they need to make complex settings on client side software, that's a problem to sub-companies. If any of you has better idea, please let me know. thanks.
