What a free call simulator gives you
A call simulator puts a rep on a live call with a customer who is not real. The value is repetition: the fortieth angry billing call is the one where the rep stops improvising and starts running a process. Doing that on paying customers is expensive, and doing it with a colleague is slow.
Call Flow's free call simulator runs in the browser with no install and no scheduling. Choose a sales, support, or call center scenario, hold the conversation in text or voice, and get a five-dimension score with quoted evidence pulled from the transcript.
It is the same engine teams pay for, just with the guest scenarios unlocked. If you want the free mock call flow specifically, the mock call practice page is the shortest route in.

Common questions
Is the call simulator actually free?
Yes. The guest scenarios run without an account or a credit card. Paid plans add team management, supervisor review, custom scenarios, and voice minutes at scale.
Do I need to install anything?
No. It runs in the browser. Voice mode needs microphone permission and any headset or laptop mic.
Is it for sales or call center reps?
Both. The scenario library covers cold calls, discovery, and closing on the sales side, plus billing disputes, cancellations, and escalations for support and call center teams.
How is the call scored?
Each call is graded across five dimensions with a short written rationale and quoted lines from your transcript, so the feedback points at something specific.
Can I practice the same call twice?
Yes, and you should. The caller temperament changes between runs, so the same scenario does not play out identically.
What is the difference from mock call practice?
They are the same engine. The mock call practice page is aimed at reps searching specifically for mock calls, this one at anyone looking for a call simulator.
