I have used the same ongoing call for years now with Eagle Teleconferencing and things have always gone smoothly and just as planned. I recently added entry and exit tones onto our call and they made it even better. You know when someone joins your call and you know when someone leaves so you always know if your listeners are losing interest, and the speaker needs to pick it up a little. Eagle so many features to make their calls great. Check them out, you wont regret it.
