13805: Trial account call duration exceeded 10 minute limit

This warning appears when a Voice call on a trial account reaches the 10-minute maximum. Trial calls are limited to 10 minutes for both inbound and outbound calls, and Twilio automatically disconnects calls that hit that limit and flags them with Warning 13805.

• The call is running on a trial account, which applies the 10-minute call-duration limit.

• Upgrade your account to remove the trial-only call-duration limit. The trial lasts 30 days or until you exhaust your free product units (for example, 100 SMS), whichever comes first. If you run out of product units before 30 days, you'll need to upgrade to continue.
