Voice SDK Error Codes
The majority of Programmable Voice error codes are five-digit integers starting at the 31000 range.
To get details on an error code, possible cause, and solutions, please visit the full Error and Warning Dictionary.
Note on JavaScript SDK Errors:
The JavaScript SDK, when applicable, will emit errors that contain a twilioError field. To view implementation information, visit the error handling sections of the Connection Reference Page's and the Device Reference Page.
This twilioError is the new TwilioError format that is now the default Error format in the new 2.0 version of the SDK. Please see the JavaScript SDK 2.0 Migration Guide for more information on this change.
