Analyze the current call routing strategy for your phone system to improve efficiency and reduce customer wait times. Review metrics such as [Call Volume], [Call Duration], and [Abandoned Call Rate] for the last [Time Period]. Identify high-traffic periods or departments with excessive wait times, and recommend changes to call routing rules or the implementation of an Interactive Voice Response (IVR) system. Provide a detailed breakdown of recommended adjustments, such as routing calls based on department size or customer urgency, and estimate potential cost savings.
