ABSTRACT:
Techniques for storing data used in making announcements in telephone communications are disclosed. In an embodiment, an announcement depends on classes of services associated with telephone subscribers. The classes of services represent call types or call features such as call-forwarding unconditional, call-forwarding busy, call-forwarding no answer, etc. A first database associates subscribed phone numbers with a class of service. A second database defines the class of services such as the call types, the telephone digit pattern in the subscribed telephone numbers, the condition for an announcement, etc. A third database defines a default class of service for use in case a phone number is not associated with a class of service in the first database.
