Correct Answer: BSince the microphone has been confirmed to work using the Voice Recorder application on the PC, the issue is likely related to the permissions settings for the VoIP application. Windows 10 has specific privacy settings that control which applications can access the microphone. To ensure that the third-party VoIP application has access to the microphone, the technician should enable the microphone under Windows Privacy settings, allowing desktop applications to use it. This step is necessary to grant the necessary permissions for the VoIP application to access the microphone, thus resolving the issue of no outgoing audio.
