Case Study: Synthflow Voice Agents Handle 500K+ Calls per Month

A top US-based CRM and sales automation platform serving thousands of businesses across industries. With over $100M in annual revenue, this company provides advanced tools for managing customer relationships, marketing automation, and sales pipelines – all within a unified platform.

In 2025, they expanded their product suite with embedded voice AI to help clients better capture leads and handle support.

The Challenge

The CRM provider’s customers were looking for better ways to manage call volumes and accelerate responsiveness across teams.

But building real-time voice automation in-house posed serious roadblocks: months of engineering work, increased technical debt, and delayed time-to-market. The team needed a fully integrated voice solution they could white-label and launch with minimal effort.

The Solution

Synthflow delivered a turnkey, white-labelled voice AI layer, fully integrated and live in just 60 days. The deployment included:

• CRM and SIP trunking integrations across 200+ platforms
• Human-like voice agents with latency under 800ms
• Enterprise-grade security and compliance (SOC2, HIPAA, GDPR, PCI-DSS)
• No-code agent deployment for rapid rollout
• Full API support for advanced customization

With no additional internal development required, the CRM provider was able to offer a fully branded voice automation feature to its customers – instantly expanding product value and opening a new revenue channel.

The Results

With Synthflow’s AI agents, the CRM platform rapidly transformed its offering – bringing voice automation to thousands of users and launching a new product line in record time:

• 500K+ Monthly AI-Powered Calls – Synthflow voice agents now handle over half a million calls per month, fully branded and automated.
