It's simple to listen to your call recordings. Where you go depends on what type of calls you want to listen to:
For any smrtPhone calls (Inbound and Outbound calls) - Access your smrtPhone Dashboard, the upper right corner, under My Account and click Billing & Logs.
For any smrtDialer calls (each Campaign has its own list of recordings) - Access the Campaign you are interested in and click on the right bottom of the page to see all Calls and recordings.
Also, you can download the call recording file from the playback screen.
Go to Account Menu > Billing & Logs > Call Logs - press the blue play button and then select download from the playback screen.
