Abstract
Abstract A central office controlled private branch exchange (PBX) is enhanced to provide more flexible services through the addition of new call vectors for controlling call processing. These new call vectors can access stored customer data to customize the treatment of incoming calls to meet the demands of individual customers. Advantageously, a broad class of new services for such systems is made available through the use of such new call vectors.
