Last night I was a participant in a conference call carried by Eagle Teleconferencing. It was a terrific expirience, and I cant wait to be try it again. Their were 600 people listening in on the call, and I felt like I was the only one. I never heard any noises from another line, the only thing i could hear was what I was supposed to and that was the moderator. I am very impressed with Eagle Teleconferencing!
