VoiceInfra: A production AI platform, engineered from scratch

This is the standard of engineering we deliver, for our own platform and for clients. Built from scratch by the engineering team at Cygen Solutions, deployed across six international markets, funded by paying customers. Explore what we can build for you.

The problem we solved

Most voice AI platforms impose the same requirement: procure a dedicated number, reconfigure your SIP trunk, replace your existing setup. They were built by AI engineers with no telephony background. We came from the infrastructure side: the protocols, the PBX internals, the operational reality of business phone systems. VoiceInfra was engineered to integrate with what businesses already run, not to force a restart.

What we built

PBX-Native Deployment

Connects to 3CX, Yeastar, FreePBX, Avaya, Cisco, and Mitel via SIP. Zero hardware changes, zero carrier switching, zero downtime. Setup takes under five minutes.

Multi-LLM Smart Routing

Use GPT-4 for complex reasoning, Claude for nuanced conversations, Groq for speed, switch anytime. No vendor lock-in, no forced AI provider.

No-Code Agent Builder

Build, configure, and deploy AI voice agents through a visual interface. Define call flows, set behaviors, and go live without writing code.

Omnichannel Support

WhatsApp, web chat, and voice, all from the same agent configuration. One platform, every channel your customers use.

Batch Calling

Automated outbound campaigns at scale. Appointment reminders, notifications, surveys: thousands of calls triggered programmatically.

100+ Integrations

CRM, calendar, database. VoiceInfra plugs into your entire stack. Agents can look up records, book appointments, and update tickets in real time.

Production results

VoiceInfra is deployed across six international markets with over one hundred native CRM and platform integrations. Setup takes under five minutes. The platform has maintained 99.99% uptime since launch, handling thousands of calls daily across the United States, United Kingdom, UAE, Spain, Turkey, and Australia.

The technology

VoiceInfra is built on a SIP-native stack with multi-provider LLM support, enterprise-grade infrastructure, and real-time audio streaming. Every component was architected and built by this team without white-label, no outsourced core.

What this means for clients

When we build your systems, this is the engineering standard we apply. Same team, same rigor, same production discipline. VoiceInfra demonstrates that a senior engineering team can design, deploy, and maintain a platform that competes globally, with paying customers, real uptime requirements, and production accountability.
