Infrastructure vs.
Pure APIs.
Generic APIs like Vapi and Retell are built for developers building apps. VoiceOI is built for BPOs building scale. Compare the seat-based economics and native dialer performance.
| Core Capabilities | VoiceOI (BPO-First) | Vapi / Retell |
|---|---|---|
| Primary Business Model | Seat-Based Economics (BPO-First) | Per-Minute API Markups (Dev-First) |
| Dialer Integration | Native AGI Handshake (VICIdial/Asterisk) | Webhooks / SIP Bridge (High Latency) |
| Latency Profile | 15ms Ultra-Low Handshake | 500ms - 2,000ms (Buffering-Heavy) |
| LLM Marketplace | Zero Markups (Bring Your Own Key) | Injected Markups on Usage |
| Concurrency Scale | 10,000+ Synchronized AI Seats | Limited by API Rate Limits |

Built For The Floor.
BPO operators don't need another per-minute bill. They need guaranteed seat capacity and native dialer handshakes.
Native Dialer Handshake
Unlike Vapi/Retell which use bridge audio, VoiceOI connects directly to your AGI system for sub-20ms handshake response.
Seat-Based Economics
Predictable monthly pricing based on concurrent seats. No per-minute markups on your AI usage. Keep 100% of your margins.
Unified Orchestration
Complete dashboard control for entire regional node meshes. Manage 10,000 seats from a single master logic layer.
