In your Better Voice dashboard, you'll find everything you need to get started with Better Voice.
On the left pane you'll see the navigation links to access any settings that are needed to configure your phone settings, your Team settings and access your inbox. You'll also see your "My Direct Line" and "Extensions" links which are used to configure how your business calls are handled.
The center pane is where you will do a bulk of your work. By default it shows your inbox contents and allows you to manage your recent calls, text messages, and search for older events. The center pane will also change to allow you to access any settings that need to be configured.
The right pane is your dialer. This phone dialer will use your computer's (or phone's) mic and speaker to make and receive calls from your Better Voice number. You can also compose text message from the dialer pane.
