Case Study: Retail Chain Implements ISI Queue Analytics, Gains Impressive 3-Year ROI


A leading Regional Retail Chain with a 50-agent call center was challenged by the escalating costs and complexities of its Avaya contact center solution. Seeking a cost-effective yet robust alternative, the chain aimed to enhance its communication infrastructure with a focus on long-term return on investment (ROI).


The chain’s Avaya solution included high costs for software licensing, hardware, and outsourced IT support. To streamline operations and realize significant cost savings over time, a strategic shift was necessary.


The chain chose to migrate to Microsoft Teams Phone with ISI Queue Analytics, integrated with Infortel Cloud. This solution was selected for its advanced analytics, ease of management, and potential for significant cost reductions. The migration plan included:

  • Adopting Microsoft Teams Queues and E5 licenses for enhanced communication features
  • Implementing Infortel Cloud with Queue Analytics
  • Reducing outsourced IT support costs by 60%
  • Including a professional services package for the transition from Avaya to Microsoft Teams Phone
