This document discusses the challenges facing corporate call centers and how cloud-based solutions may help address them. The three key challenges are: 1) a credibility gap between marketing promises of excellent customer service and the actual call center experience, 2) a sales gap in losing potential sales due to poor call handling, and 3) technology limitations of legacy on-premises call center systems. Cloud-based call centers offer lower costs, greater flexibility, and ability to provide improved customer service across multiple channels. Case studies demonstrate cloud systems can increase customer satisfaction metrics and revenue growth compared to traditional call centers. The document concludes cloud technology can help call centers overcome challenges by converging applications to reduce costs while improving customer support and sales.
