Proving experience at scale — ensuring confidence before every release in an AI-native world. Echo uses lifelike AI agents to call your IVR systems, test every path, and catch broken experiences before they reach production.
A developer deploys a small change late on Friday. It doesn't touch the sales flow directly — it isn't even in the same system. But somewhere downstream, that tiny change breaks a critical IVR path.
Over the weekend, a major promotion launches — and sales quietly flatline. By Monday morning, Slack is on fire.
Large upfront pricing packages that lock you in.
Only allow a small number of tests — not enough to catch edge cases.
Can't test real voice interactions, only simulated flows.
Only work for static, DTMF-based interactions.
Require lengthy setup and often involve expensive human resources.
Most businesses simply deploy and hope for the best.
Lifelike AI callers test your IVR the way real customers interact with it.
Run hundreds of calls at once. Test every scenario, for every number, every time.
Works with traditional DTMF, speech-enabled, and next-gen GenAI-powered IVRs.
Eliminates human-heavy, expensive, fragile test suites that break as fast as they're built.
"This won't break on Monday." — the only metric that matters.
From test configuration to continuous monitoring, Echo gives you complete confidence.
Lifelike AI callers test your IVR the way real customers interact — with voice, DTMF, and natural conversation.
Run hundreds of simultaneous test calls. Cover every scenario, every number, every time — in minutes, not days.
"This won't break on Monday." Know your IVR works before customers find out it doesn't.
Trigger tests on every deployment or run them on a schedule. Continuous monitoring that fits your workflow.
Every test run produces scores and detailed results. Track reliability trends over time and catch regressions instantly.
No simulations or mocked endpoints. Echo places actual phone calls through your production IVR systems.
Build test cases manually with full control — or import experience maps from Resonance CX to auto-generate tests for every path.
Launch tests on demand or on a schedule. Control frequency, timing, and scope.
Hundreds of AI agents call your IVR systems simultaneously — real voice, real conversations.
View scores, review call details, listen to recordings, and track reliability trends over time.
Optimize tests, adjust expectations, and re-trigger — building confidence with every cycle.
Configure tests manually — or let Resonance CX automatically crawl your IVR and generate tests for every path.
Build test cases yourself. Define phone numbers, expected paths, caller personas, and success criteria. Perfect for teams that know their IVR inside and out and want precise control over what gets tested.

Already have your IVR mapped with Resonance CX? Echo automatically imports your experience maps and generates comprehensive test cases for every path — no manual setup required. As your IVR evolves, re-crawl with Resonance and Echo updates your test suite automatically.


Resonance CX crawls your IVR and maps every path. Echo takes those maps and tests them continuously. Together, you get complete discovery and continuous validation — a closed loop of IVR confidence.
