You can download call recordings, either as a video or audio file, from the action menu 
in the top right corner of a call page.
Before the call starts to download, you'll be warned that the file may contain personal information subject to various data protection regulations. Please make sure that any personal information in the file is kept confidential.
Note
The ability to download a call recording is set in the permissions profile. If you don't see it and think you should, contact your Gong admin.
