Test your voice agents before moving them to production.
Vattara calls your voice agent with synthetic callers from an industry-specific library of use cases over real telephony. Listen to every conversation before you approve.
Failed calls get transferred to your team anyway. You end up paying for the agent and the person.
False-positive dispositions
Reporting failed calls as successful
The call ended, so the dashboard marks it completed. But the customer left without what they needed, and no one knows.
Lost revenue
Customers hanging up mid-call
The agent takes too long or mishears the caller. The customer gives up, and takes the sale, booking, or renewal with them.
How we evaluate
Every call, measured five ways.
We run each agent through realistic call simulations, then score every call across five dimensions: 26 signals in all, including the ones a transcript can’t catch.
We call this framework CLEAR.

The booking went through. The call didn’t feel like one.
Each letter is a set of measured signals, not a single score — 26 in all.
Every simulated call is scored the way production judges it: the full latency chain, load, coverage, and outcomes.

The Vattara Suite
One platform for the voice agent lifecycle
A good voice agent goes through rapid testing, tight integration with tools and agents, and continuous monitoring. Vattara carries it through all three, so organisations deploy voice agents with confidence.
Vattara Evals
Live
Test
Pilots stall for weeks because nobody can prove the agent works before launch. Evals runs simulated conversations against your agent, across every persona, accent, and edge case, before a single real customer calls.
Tool calls misfire silently, triggering wrong or incomplete actions. ToolBox validates every connection your agent depends on, from APIs to CRMs to schedulers, and surfaces the one that breaks mid-transfer.
Catch integration failures before your customers do.
Most live-call failures go unexplained, and QA cannot audit every call. Observe watches every deployment in production, locates the moments that went wrong, and explains why.
