Overview

emutel|Harmony is a powerful Telecommunications Test Platform and Bulk Call Generator for VoIP and POTS; it combines comprehensive load testing and network simulation, detailed protocol analysis, extensive call statistics and quality of service measurements.

This enables integrated testing for both packet and circuit-switched traffic, and a single system can provide anything from 5 to 75 ethernet interfaces, 8 to 120 E1/T1 interfaces, 16 to 240 analogue interfaces, or any combination. Harmony is capable of generating up to 75,000 SIP calls or 3,600 ISDN calls simultaneously - 6 million ISDN or 8 million SIP calls per hour.

The system is a highly efficient, cost-effective and flexible tool, invaluable for use in the development, performance verification and pre-deployment testing of many types of VoIP, ISDN and analog equipment.

• Design, schedule and run multiple test scenarios to verify performance, functionality, capacity and interoperability.
• Bulk Call Generation and Termination for high capacity tests.
• Unlimited level of scalability with no performance degradation.
• Network Simulation provides comprehensive test capabilities.
• Simultaneous wrap-around TDM and VoIP testing.
• Multiple Protocols and Traffic types including SIP, H.323, ISDN and analog support.
• Highly intuitive ScriptComposer Application for flexible, fast and user-friendly script building.
• Load Profiling to re-create realistic call patterns.
• Built-in Protocol Analysis for quick and easy fault finding and debugging.
• Transmit and receive tones, speech and video with wide range of CODECs.
• Real time statistics show call rates per second, completed call attempts, packet loss, delay etc.
• Verify Quality of Service on both TDM and VoIP channels using PESQ.
