AI Calling Agent — Voice Automation at Scale

We deployed an AI voice agent that handles unlimited concurrent inbound and outbound calls with human-like quality — reducing wait times, automating reminders, and logging all interactions directly to CRM.

AI Calling Agent — Voice Automation at Scale

The Challenge

The client's call centre was under-staffed during peak hours, leading to high abandonment rates and customer churn. They needed a voice automation layer that could handle repetitive call types at scale without sacrificing call quality.

What We Built

Zarrx built a custom AI Calling Agent using advanced voice synthesis and NLP. The agent handles outbound appointment reminders, lead qualification, and payment prompts, while routing complex calls to live agents with full context. All calls are logged automatically to Salesforce.
