When working with calls in Azure Communication Services, you might encounter issues that affect your customers. To help with this, Azure Communication Services provides a feature called User Facing Diagnostics (UFD) that you can use to examine various properties of a call to determine the issue.
User Facing Diagnostics are events that indicate some underlying issue, such as poor network quality or a user has their microphone muted. The UFDs can cause a user to have a poor experience. After a User Facing Diagnostic fire, consider giving feedback to the end-user about the underlying issue. However, the User Facing Diagnostic output is informational only, and the calling stack doesn't make any changes based on a User Facing Diagnostic being fired.
