13616: Record: playBeep must be true or false

Twilio returns this warning when your <Record> TwiML sets playBeep to a value other than true or false. The playBeep attribute controls whether Twilio plays a sound before recording starts, and its default value is true.

• The <Record> verb includes playBeep with a value other than true or false.
• The playBeep attribute was provided with a value outside the allowed values for <Record>.

• Set playBeep="true" if you want Twilio to play a beep before the recording starts.
• Set playBeep="false" if you do not want Twilio to play a beep before the recording starts.
• Update your <Record> TwiML so the playBeep attribute uses only true or false.
