Now that you are able to place calls to the outside world with the Trunks and Outbound Routes you have created, you might want to control how the outgoing calls are placed. You might want to restrict outgoing calls to a schedule, or you might want only certain end-users to be able to dial certain numbers. For all of this, you can use what we call a Class of Service. Classes of Service are an essential tool for you to have full control of the outgoing calls from your VitalPBX installation.
Classes of Service are composed of three main options Feature Categories, Dial Restriction Rules, and Route Selections. We can configure any of these three features to create our Class of Service.
