The use of our Web-Scheduled Standard service is free. In order for conference participants to reach our service, each one must call a dial-in number assigned by FreeConference. This number may be local or long distance, depending on their location. The only costs for the audio portion of the call are whatever long distance rates are charged by each individual conference participant's long distance carrier (Sprint, MCI, AT&T, etc.). We do not require the use of any specific carrier, nor do we know what rates you pay on your calling plan.
