How to change the destination to audio files from watch protocol

Hi! What I need to change the media folder of my traccar server and receive the audio files?

Path to the media folder is in the default config file.

I want to use a container like Amazon S3, it is possible? pass URL in the path to the media folder?

You can't do URL, but you can probably use some tools to mount your container to local file system and then use it for the folder.

Thanks for the clarification!
Is there any notification in traccar when a media file is received?

No, there is no notification, but you will see it in status.

Which status?

State panel.

I have a implementation to notify when a media file has been received.
