Eagle Teleconferencing has a feature where you can put your call into Security mode. This works great for when I am ready to start my lecture. With just a press of a button I can activate this feature. This makes sure that no one else is allowed onto my call once started. This has really eliminated callers coming in late and causing excess noise. Thank you again Eagle for another way you make my conference call that much easier. I can always count on Eagle to stay ahead of the competition!
