Chapter 1 described the essential components of a call center and the importance of technology, particularly the integration of several technologies, in the implementation and operation of the call center and in providing the range of services required to manage customer communications effectively. This chapter describes the evolution of call center technologies and provides a detailed analysis of these technologies and how they function as well as how they can be applied to meet call center requirements.

Advances and changes in technology have made many new features available to call center operations, providing increased efficiency and better opportunities for serving customers and empowering CSRs with the capability of better managing customer interactions. Most call centers use several systems and applications with specialized functions. In parallel with these advances in technologies that are internal to the call center, more "intelligent" network services offered by carriers make possible the routing of calls based on a wide range of criteria area code or prefix, dialed number identification service (DNIS), time of day, day of week, and other parameters that are under the control of call center management. Call allocation facilities are also available that can program the network to send defined percentages of calls to selected sites.

Other significant changes that have occurred in the call center because of the availability of enabling technologies include the following:

• Accessing of applications using icon-based GUI windows, allowing for simultaneous task execution

• Scanning and retrieval of on-screen documents, a process that increases the speed of document...
