IR Prognosis StressTest   

StressTest load testing assesses UC, IVR & contact center performance under peak traffic conditions

How IR Prognosis StressTest Works

StressTest™ is a cloud-based, managed, load and performance testing service for voice systems that provides the insight you need to assess, tune, and verify contact center performance and go live with confidence.

StressTest goes beyond component level testing to deliver comprehensive performance verification of production systems and environments. Test calls are generated remotely and access your system via the Public Telephone Network, just like real Customers, following a carefully defined test case script to access and interact with your communications technology. By testing IVR and contact center systems from the outside-in, StressTest services reveal the customer perspective of system performance under real-world conditions.

Whether it’s a new service, recovery after repair, or upgraded self-service capabilities, StressTest allows you to proactively identify issues and manage the risk associated with implementing complex UC and contact center solutions.


Features of StressTest Performance/Load Testing

  • Participate in flexible test sessions to suit your schedule
    Tests and retests ensure the solution performs as expected under load and verifies capacity, performance, stability, and resilience.

  • Access to comprehensive test call results
    The results of each call, including information about step-by-step response times, are captured and made available in real-time via the web, and after the test session via detailed reports. Complete test call recordings available via the web let you hear what really happened during each test call.
