CALL PROCESSING SYSTEM WITH INTERACTIVE VOICE RESPONSE

摘要

A call processing system (38) has an architecture that provides interactive voice response to callers before further routing of calls. Ports (47) connected to the telephone network (22) are coupled to processors (46) that perform interactive voice response without a distributive switch therebetween. Redundancy is provided at component and system level and an uninterruptible power supply (76) and transfer panel (74) are connected to a supplemental generator (72). Local call processing system are connected by multiple networks to remote call processing systems with a redundant distributed database accessible to the processors (46) and resource servers for providing other services, such as text-to-speech and speech recognition. A resource management unit (60) detects, stores and reports resources available on each system to higher level call processing systems connected via the network. Addresses of call processing systems at least at higher levels are accessible by a local call processing system for redundancy.
