A Web-based call routing management workstation application which allows authorized customers to control toll free routing and monitor call center status. An architecture including one or more web servers located in a firewalled demilitarized zone (DMZ) as communications medium between the customer workstations at the customer sites and the enterprise back-end applications providing the call routing management services, provides a secure infrastructure for accessing the enterprise applications via the otherwise insecure public Internet. The present invention enables creation and management of call by call routing rules by a customer with a workstation having an Internet access and a supported Web browser. The customized rules may be tested and/or debugged via the Web-enabled workstation, using a debugger/tester which runs the routing rules under a simulated environment. In addition, customers may provision hierarchies for their business; create, modify or delete agent pools; manipulate capacity tables; and define quota schemes, value lists and schedule tables, all at the customer site via the Web-enabled workstation. The present invention also enables the customers to view near real-time displays of call center ACD statistics and peg counts based on routing rules, as well as, run provisioning and statistical reports on provisioning and statistical data and also to extract the data for further analysis. Additionally, the present invention supports foreign language and branding features on a graphical user interface. An infrastructure is provided which enables secure initiation, acquisition, and presentation of the call manager functionalities to customers from any computer workstation having a web browser and located anywhere in the world.
