How do I navigate recorded calls?

You can jump to any time of the recording by clicking within the bar above the Play/Pause controls.

This bar will change colors from gray, to orange, to red. Gray shows the portion of the recording that is still loading, orange shows how much of the recording is loaded but not yet listened to, and red shows how much of the recording has already been heard. You will find the progression time in the lower right hand corner of this bar.
