13235: Dial->Conference: Invalid beep value

This warning occurs when you set the <Conference> beep attribute to a value Twilio does not accept. Use only true, false, onEnter, or onExit to control whether notification beeps play when participants join or leave a conference.

• The beep attribute in your <Dial><Conference> TwiML was set to a value other than true, false, onEnter, or onExit.
• Your application generated the beep value dynamically and introduced a typo, unsupported casing, or another unsupported value. Twilio only accepts true, false, onEnter, or onExit.
• You passed an unsupported beep value when creating or updating a conference participant through the Conference Participant API.

• Update your <Conference> TwiML so beep uses one of the supported values: true, false, onEnter, or onExit.
• Choose the value that matches the participant experience you want. Use true for beeps on join and leave, false for no beeps, onEnter for join only, or onExit for leave only.
• If you set conference options through the Conference Participant API, send the same supported beep values there and review any application logic that builds the request.
