AI voice agents are moving from demos into real business workflows. But what actually makes an AI phone call successful?

To find out, DialNexa analyzed more than one million AI-assisted business calls across India. The dataset included inbound and outbound conversations, with use cases ranging from pre-sales lead qualification to webinar and event follow-ups.

The findings suggest that voice quality is only the beginning. Timing, retries, latency, language handling, and conversation design can determine what happens after someone answers.
