Calling party identification announcement service

摘要

Calling party identification announcement service (CPIAS) provides an announcement of the caller's name to a called party, so that the called party may accept of reject a call. This invention relates to arrangements for providing CPIAS using centralized announcement synthesis apparatus, under the control of a data base (in accordance with the principles of intelligent networks), within the basic call processing arrangements of the public switched telephone network, without requiring users of the services to have two telephone numbers. Billing entries for the use of the announcement service are made under the control of the terminating switch so that these entries can be readily combined with other billing entries for the called party in order to generate a bill for that party.
