Many parameters are available for setting custom sounds to play from within the conference bridge when certain activities occur. All sounds are played to individual caller channels and not to all parties in the conference, with the exception of enter-sound and exit-sound, which are played to all participants.

All sound files are specified with the format: <param name="sound-name" value="file.wav"/>

• muted-sound: This sound is played when a caller has been muted.
• unmuted-sound: This sound is played when a caller is no longer muted.
• alone-sound: This sound is played to a caller when they are the only remaining party.
• enter-sound: This sound is played to all members when a new caller joins the conference.
• exit-sound: This sound is played to all members when a caller leaves the conference.
• kicked-sound: This sound is played when a caller is kicked out from the conference.
• locked-sound: This sound is played to callers who try to join a locked conference.
• is-locked-sound: This sound is played to conference participants when a conference is locked.
• is-unlocked-sound: This sound is played to conference participants when a conference is unlocked.
• pin-sound: This prompt is used while asking for a conference pin.
• bad-pin-sound: This sound is played when an invalid PIN number is entered.
• perpetual-sound: A special setting-this plays a sound in a continuous loop forever. This can be used to broadcast sales or emergency messages to callers.
• moh-sound: A file or resource handle that plays a particular music-on-hold stream to the conference, when there is only one member in the conference. When a second member joins, this audio will stop, unless the mod-wait settings have been specified (as mentioned earlier).
• max-members-sound: If someone tries to join a conference that already has the maximum amount of members, this file is played.
