Sometimes you might find yourself meeting with someone on a slower internet connection, have out of date software, or simply an old device that can cause your calls to be choppy.
Call Optimization feature should help reduce choppy calls. It is only available to paid users.
You can switch to Call Optimization while on a call. Move your mouse and the call controls will pop up. Hover over the control that says either HD or SD. The 3 video settings will be displayed. Choose OP to enable Call Optimization.
