Where can I find the Call recordings of my campaign?

Call recordings will be available in the results tab of your Call Center campaign. You can click on the campaign, navigate to Results > Notes. 

Note: Calls will be recorded only if Record all Calls option is enabled in Campaign settings.

Once you click on Notes, It will show you a dialog box that displays the details of the contact, the outcome of the call, and the audio recording section which includes a link for the call recording. 

You can click on the text "Audio Recording" and it will turn into a small player as in the below image and you will be able to listen to the recording. Alternatively, you can copy-paste the URL on your browser to download it to your device.
