Abstract: Telephone calls within one or more telephone networks (or portions thereof) are animated in real time as they occur, or over some past period in real time or at a user-selected speed. Each animated call displays the call's progress from its first connection to its final disconnection, along with intervening connection delays and transition events (e.g., transfers, holds, conferences, etc.). Animated display of multiple concurrent calls allows network administrators to easily and intuitively diagnose telephone network issues and more easily devise solutions, particularly where such display is provided in combination with concurrent measures of telephone network efficiency.
