This error returns the message `record must be "true" or "false"`. For ``, supported recording values are `do-not-record`, `record-from-answer`, `record-from-ringing`, `record-from-answer-dual`, and `record-from-ringing-dual`. For backward compatibility, `true` maps to `record-from-answer` and `false` maps to `do-not-record`. ### Possible causes * Your `` verb sets `record` to a value that is not one of the supported recording options. * Your application sends a typo, unexpected capitalization, or extra characters in the `record` value, so Twilio cannot match it to a valid option. * Your application builds TwiML dynamically and the variable used for `record` resolves to an empty or unsupported value at runtime. ### Possible solutions * Update the `` verb so the `record` attribute uses a supported value such as `do-not-record`, `record-from-answer`, `record-from-ringing`, `record-from-answer-dual`, or `record-from-ringing-dual`. * If you use the legacy boolean form, set `record="true"` to use `record-from-answer`, or set `record="false"` to use `do-not-record`. * Review any code or template logic that generates your TwiML and confirm it outputs the exact `record` value you expect before Twilio processes the `` verb. #### Additional resources * [TwiML Voice: ``](/docs/voice/twiml/dial) * [Recordings resource](/docs/voice/api/recording) * [How to Record a Phone Call with Twilio](https://help.twilio.com/articles/223132867-Recording-a-phone-call-with-Twilio)
