Add upload audio files to call

[alhdo]

It would be nice to upload audio as support of text in phone calls
Sometimes call is long more than 2 minutes. It would be nice to upload the audio files if we have it. Not required field but optional.

• Sometimes i don't want to describe all the conversation
• The text is cool but i usually make a summary of the call

Proposed solution
I would like to able to provide an mp3 file or ogg file for the call, In the future we can think about using an Machine Learning to translate it to text but not required for the moment.

I am a developer
