Media Handler and Storage
The Media Handler manages your captured audio storage. The Media Handler receives audio from the Audio Connector and processes it according to Storage and Export Policies. When requested by the application, the Media Handler retrieves and delivers the audio for playback.
The Media Handler receives audio from the Audio Connector in PCM 16 stereo format, ensuring consistent storage and processing of call audio. The conversation audio has a Conversation ID associated with it, which is used to identify the call throughout the system, and allows the system to query specific calls and tie conversations together.
Using MinIO, the Media Handler sends the audio over GRPC to the configured S3 storage, ready to be retrieved when needed. When a user opens a live or captured call in the UI, a request is sent to the Media Handler with the Conversation ID to retrieve the call and stream it to the application via GRPC.

Note
The above summarizes how conversation audio is processed and stored by the media handler for a Communication Recording Agent system. The Media Handler is a Administration Platform component and can be used by other applications.
