13230: Dial->Conference: Invalid muted value

This warning occurs when the muted attribute on <Conference> is set to a value other than true or false. The muted attribute controls whether a participant can speak in the conference and defaults to false.

• The muted attribute on <Conference> was set to a value other than true or false.
• Your application included muted in generated TwiML even though the participant did not need to join muted. When you do not set muted, Twilio uses the default value of false.
• You need to change mute state after the participant joins, but the initial <Conference> TwiML is being used with an unsupported muted value instead of a valid boolean value.

• Set the muted attribute on <Conference> to true or false only.
• If the participant should join unmuted, remove the muted attribute and let Twilio use the default value of false.
• If you need to mute or unmute a participant after they join the conference, update the participant by using the Conference Participant API.
