31000: Generic error

Error 31000 is a generic Programmable Voice error in the 310xx series. More details are often available in the Twilio Debugger or, for the JavaScript SDK, in the twilioError field.

• A non-specific condition occurred in the Programmable Voice SDK or platform during call setup or operation, and no more-specific 31xxx code was emitted. Refer to the Twilio Debugger details or the SDK's twilioError field for additional context.
• The underlying issue surfaced elsewhere in logs as a related 31xxx error, for example connection or signaling problems, which should be identified and addressed based on the more specific code shown in your logs.

• Check Twilio Debugger error logs in Console under Monitor > Logs > Error logs to review the event, its description, potential causes, and suggested solutions.
• If you use the Voice JavaScript SDK, inspect the twilioError field on emitted errors for diagnostics that explain the generic 31000 condition.
• Use the troubleshooting guidance for Programmable Voice to examine request and response details, identify failing webhooks or TwiML, and isolate where the issue occurs in the call flow.
• When you open a support case, include recent Call SIDs, Notification SIDs, relevant error codes, and SDK logs so that Support can investigate quickly.
