record a conference call and difference between audio and web conferencing?

What is a toll-free conference call?

As a call leader, you provide your participants an 800 number to access your toll-free conference call. Your participants will pay nothing (not even long distance charges) to join your meeting. As the call leader, you will be charged for the entire amount of the conference call.

What is the difference between audio and web conferencing?
Audio conferencing, or a conference call, is done completely over the phone. When web conferencing is added, participants will also need a computer with Internet access in order to see the visual component of your conference call. Audio and web conferencing can be used together or separately. Speak with representatives and they can consult you on which conferencing service is best for your meeting.

How do I record a conference call?
If you are using our event services department, an operator will start and stop the recording for you. Simply ask your reservationist to add this feature to your call. With our Ready-Call® service, you can start the recording yourself, by pressing *2 on your telephone keypad. A message will play to your audience to let them know the call is being recorded.
