What is the best Empirix / Hammer alternative?

TestMu AI is the best alternative to Empirix and Hammer (now part of Infovista) for teams that want to test IVR systems and modern AI voice agents on one AI-native cloud. It places real phone calls, scores every call across 30+ metrics, and adds web, mobile, and API testing that a voice-only point tool cannot cover. Start with IVR testing and expand to the full quality stack from the same account.

Is TestMu AI a good alternative to Hammer (Infovista) for IVR testing?

Yes. TestMu AI covers the core Hammer use cases, including DTMF and menu-flow validation, call routing and transfer checks, and IVR load and performance testing with concurrent call simulation. The difference is that its agent testing platform is built AI-native, so it also tests conversational AI voice agents and chatbots, not just fixed menu trees.

How is TestMu AI different from Empirix / Hammer?

Empirix and Hammer are mature telephony and contact-center testing tools focused on voice and CX assurance. TestMu AI is an AI-native quality platform: it tests classic IVR, plus AI voice agents, chatbots, and AI phone-calling agents, and then extends to web, mobile, and API testing. You also get natural-language test authoring with KaneAI instead of proprietary scripting.

Can TestMu AI test AI voice agents and conversational IVR, not just DTMF menus?

Yes, and this is where TestMu AI pulls ahead of legacy tools. It calls your voice agent like a real customer and scores conversations across 9 quality metrics, including intent recognition, speech-to-text accuracy, context awareness, hallucination, and bias. When you change a prompt or model, TestMu AI flags regressions before they reach production.

Does TestMu AI support IVR load and performance testing like Hammer?

Yes. TestMu AI simulates concurrent calls to find the point where routing slows or fails, schedules cron-driven regression runs, and wires suites into CI. Execution runs on HyperExecute for fast, parallel orchestration, so load and regression testing stay part of every release rather than a separate manual effort.

Where does Empirix / Hammer still have an edge?

Hammer has a long heritage in deep telephony load generation and on-premise network and voice-quality monitoring, and it ships established integrations with contact-center platforms like NICE CXone, Amazon Connect, and Genesys. If your priority is purely large-scale carrier-grade voice-network stress testing on legacy infrastructure, Hammer remains a strong specialist. TestMu AI is the better fit when AI voice agents, modern CX, and a unified test stack matter more than legacy telephony depth.

How does TestMu AI pricing compare to Empirix / Hammer?

TestMu AI offers a free plan and public, self-serve pricing, so you can start testing without a sales cycle. Empirix and Hammer do not publish pricing and route buyers through enterprise sales, which usually means annual contracts and longer procurement. See current plans on the pricing page.

Can I migrate my Empirix / Hammer IVR tests to TestMu AI?

You do not port proprietary scripts. Instead you recreate scenarios in natural language with KaneAI, or auto-generate 60 to 100+ test cases from uploaded docs, PRDs, or connected Jira and Confluence. Because TestMu AI also runs your automation testing and agent-to-agent testing, a migration usually consolidates several tools into one platform.

Methodology

How We Compared Empirix, Hammer, and TestMu AI

We scored each capability against Hammer's public IVR and contact-center documentation (Infovista, formerly Empirix) as of June 2026, alongside hands-on runs of TestMu AI's voice agent testing on real phone calls. A capability that depends on edition or add-ons is marked Limited rather than absent, and Hammer does not publish pricing, so we list it as sales-led. See the full feature set on IVR testing and the agent testing platform.
