Why teams pick PyAI over Twilio Voice AI
The AI voice layer - not another phone system with AI bolted on.
AI agents are the product
Pay for AI minutes and outcomes, not per-seat phone licenses with AI packaged as an add-on. Omni runs the agent end to end.
Bring your number, or use managed telephony
Keep your carrier or SIP, or use PyAI managed telephony at $0.01/min - no separate carrier negotiation required.
Developer-first and OpenAI-compatible
Build with clean APIs and an OpenAI-compatible surface instead of clicking through a closed phone-system console.
Every call becomes data
Trace scores 100% of calls for compliance and QA; Recap turns each call into summaries, dispositions, and CRM-ready next steps.
