I just set up a new account with Eagle Teleconferencing. I have a conference call that is set up 24/7, so I never have to call and set up a new conference call. I always have a line any time I need to. As the moderator of the call, I can log onto the internet and I am able to see all the phone lines and phone numbers of callers that call into the conference call. It also gives me controll to mute and record the conference call myself. Also, if there is a line causing a problem, I can find that line and hang them up or mute just there line myself
