IVR performance testing

Optimizing IVR performance is crucial for businesses relying on call centers or customer calls.
It serves as a potential bottleneck, particularly during surges in call volumes triggered by promotions or weather changes.

Given the prevalence of automated operations, we specialize in assessing how adeptly your IVR systems manage diverse loads during peak times.

Stats don’t lie

Leveraging advanced technologies like NLP and AI, IVRs globally contribute to lowering organizational costs, with each IVR call equating to the cost of six or seven person-to-person calls.
In 2020, the global IVR market reached $4.2 billion, with a projected CAGR of 7.9%, expected to hit $6.7 billion by 2026.

The U.S. IVR market, valued at $1.4 billion in 2021, represents 31.4% of the global market share.
Increasing IVR containment rates by 5% to 20% can result in a substantial 10% to 30% reduction in call center costs, providing a robust return on investment.

When you might need it

At PFLB, our comprehensive IVR testing services cover a spectrum of crucial aspects, ensuring your system’s seamless performance:

System go-live

We provide performance testing services to guarantee that your mobile application can effectively manage the load when it goes live in the store.

Continuous performance testing

Establishing a testing process for every new application release, even if it’s been tested before launch, is vital.
This proactive approach ensures the early detection and resolution of any performance issues, preserving a seamless user experience.

Preparation for peak loads

We can assist you in getting ready for peak loads during events like holidays and advertising campaigns, ensuring your application can smoothly handle increased traffic without any hiccups.

What we could offer you

IVR testing is essential to ensure your system functions flawlessly, especially during high call volumes or promotional events.
We provide expertise to guarantee your IVR performs reliably in all situations.
We rigorously evaluate your app’s back-end performance by simulating a specified user load. Our PFLB platform technology enables us to emulate the VoIP protocol, making calls from both local and internet networks.

Load Testing Tools for IVR Systems
Mar 20, 2019

Around the world, JMeter and LoadRunner remain some of the most popular tools for load testing. These are truly excellent tools and most performance engineers use them.
When choosing load testing tools the main question is whether the tool supports all the required protocols? When it comes to HTTP, the selection of tools is enormous, including excellent cloud solutions that make it possible to create a load simultaneously from different points on the planet. For less common protocols the number of suitable tools shrinks considerably. In these cases, the indisputable leader is LoadRunner, an HP product and the de facto standard in the enterprise segment.
