The IP Contact Center leverages IP to flatten and consolidate contact center infrastructure, removing expensive network charges and running many locations from one centralized set of applications (or maybe two for redundancy). Home agents, satellite locations, outsourced resources, and resident experts are then easily added as extensions to the same contact center, maintaining centralized management and decision-making. With the unique, evolutionary 1-TO-ALL approach to IP, contact centers can get started at their own pace, choosing whatever mix of existing traditional and new IP telephony makes sense. Some 1-TO-ALL customers have realized dramatic operational cost savings - tens of millions of dollars in some cases.
