You can assign a Direct Dial phone number to your Better Voice account. Direct Dial numbers immediately ring to you (according to your Find Me settings) and will go to voicemail if you do not answer. You can configure your Direct Dial numbers two ways:
On the "My Direct Line" page, under the Direct Dial Numbers section, click on the "Choose Existing" button to assign an existing virtual number in your account. Or, you can choose to "Purchase New Number" as well.
You can also assign direct dial numbers to your Account from the "Phone Numbers" page in the app. This provides a list of all of the virtual numbers in your account. Use the dropdown form option to select which Extension, or user, a phone number should be assigned to.
