When you define Scenarios and Routing Tables and other fundamental Soft Switch mechanisms, you will notice that you are required to
specifyScenario Group parameters. Scenario Groups—which are pre-defined for you by Startel —are used as a means of identifying or assigning
the “entry points” that should be used for the calls that flow in and out of the Startel system. Most sites will use two primary Scenario Groups—
Incoming, and Outdials —which differentiate between incoming and outgoing calls. Additional Groups are sometimes used to differentiate between different types of incoming or outgoing calls. For example, a Central Office group may be used for incoming DIDs, and an Internal
group may be used for SIP phones. In any case, Startel will instruct you on how to use the Scenario Groups that are defined and best suited for your particular system.
