 The Code and SubCode values within the ResultInformation of a callback event indicate the status of an operation. These values are identical and can be used to determine the reason for an event, such as a call being disconnected. For details on specific disconnection reasons, refer to the list of codes provided at [Call end troubleshooting codes](../../../resources/troubleshooting/voice-video-calling/troubleshooting-codes.md?pivots=callend).
