There is no cost for these Audio Conferencing tools. Each individual Moderator can have them set per his/her own preference, and they can be changed at any time. Entry/exit tones distinct tones let you know when participants enter or exit the call. The default is to have the tones activated. If you conduct large calls (30+ Participants), you might consider removing the tones. Name prompt Incoming participants are prompted to record their name prior to entering the call. By pressing *8, the Moderator can listen to an automated roll call, hearing the Participants' recorded names. Name announces if you choose "Name Prompt", you can have the participants names played into the call as they enter or exit. This feature adds to the security of the call. Live entry/participant wait The Moderator has the choice of allowing Participants to communicate with one another before the conference begins, or have them wait with music on hold until the Moderator has entered. Once the Moderator passcode has been entered, all participants will be immediately connected. Reference number/charge code Select this option when you need to associate individual teleconferences to specific accounting codes, matter, customer or file numbers, etc. You will be prompted to enter a numerical code of your choice when you enter your teleconference. You can then track and report the teleconferencing usage by that Reference Number. Video Conference Studios
