13699: Record: Invalid trim value

This warning appears when a Voice recording configuration includes a trim value that Twilio does not accept. Use trim-silence or do-not-trim for both TwiML <Recording> and the Recordings resource.

• The trim parameter contains a typo or another unsupported value.
• The request is using a trim value that does not match the Voice recording surface you are calling.

• Set trim to trim-silence if you want Twilio to remove leading and trailing silence, or do-not-trim if you want to keep the full recording.
• Confirm whether you are starting the recording with TwiML <Recording> or with the Recordings resource, then use the documented trim values for that surface. TwiML <Recording> defaults to trim-silence; the Recordings resource defaults to do-not-trim.
• Resend the request after correcting the trim value.

• TwiML Voice: <Recording>
• Recordings resource
