Platform Capabilities

The Complete
Voice AI Infrastructure

From low-level telephony protocols to high-level LLM orchestration. We've built the full stack so you don't have to.

~600ms

Turn-Taking Latency

Optimized endpointing algorithms ensure the AI responds instantly, mimicking natural human conversation gaps.

99.99%

System Uptime

Redundant telephony carriers and edge-deployed WebSocket servers ensure your agents are always online.

10k+

Concurrent Calls

Elastic infrastructure that scales automatically. Handle thousands of simultaneous calls without jitter.

The Audio Engine

Real-time Interruption Handling

Achieving a "magical" voice experience requires handling interruptions gracefully. Our VAD (Voice Activity Detection) models run on the edge to detect speech in milliseconds.

  • Instantly clears audio buffer when user speaks.
  • Context aware: The AI knows it was interrupted and adjusts its response.
  • Noise suppression filters out background noise automatically.

Function Calling

Give your agent real tools

Invaria agents don't just talk; they do things. Define custom functions in your LLM config, and our infrastructure executes them during the call.

  • Book appointments directly to your CRM.
  • Look up order status or account details.
  • Send follow-up emails or SMS after hangup.
