> ZeroVoice — programmable voice and SMS platform for AI agent communication

# ZeroVoice

ZeroVoice is AINative's programmable telephony platform. It gives your AI agents the ability to **make and receive phone calls**, **send and receive SMS**, and manage phone numbers — all through a REST API or MCP tools.

Built on Twilio, ZeroVoice adds multi-tenant isolation, compliance guardrails (DNC/TCPA), call recording with transcription, IVR flows, real-time analytics, and a supervisor dashboard.

## Key capabilities

| Capability | Description |
|---|---|
| **Outbound calls** | Place calls with circuit-breaker protection and per-tenant concurrency caps |
| **Inbound routing** | IVR menus, queue-based routing, agent assignment |
| **SMS messaging** | Send/receive SMS with DNC enforcement and compliance keywords |
| **Phone numbers** | Search, purchase, release, and configure routing for numbers |
| **Call recording** | Record calls with legal-hold support, transcription, and sentiment analysis |
| **Voicemail** | Automatic voicemail outside business hours with transcription |
| **MCP bridge** | 25 MCP tools for agent-driven telephony |
| **Analytics** | Call volume, agent performance, sentiment trends, disposition breakdowns |
| **Compliance** | DNC list management, TCPA guards, GDPR export/delete, PII audit logging |
