Twilio Integration for AI Voice Agents + Phone Call Automation

Connect your AgentVoice voice agents to Twilio for enterprise-grade telephony with global number provisioning, SIP trunking, and programmable voice.

Enterprise-grade telephony infrastructure for your voice agents

AgentVoice connects natively to Twilio’s Programmable Voice and Elastic SIP Trunking, giving your voice agents access to the same carrier-grade telephony infrastructure used by hundreds of thousands of businesses worldwide. Bring your own Twilio numbers, port existing numbers, or provision new ones in over 100 countries — and connect them to AI voice agents that handle calls from the moment they ring.

Twilio handles the hard parts of telephony: global PSTN connectivity, number provisioning, call recording, compliance, and carrier redundancy. AgentVoice handles the conversation. Together, you get AI-powered call handling on infrastructure that scales from your first phone number to thousands of concurrent calls without touching a PBX.

What your agent can do

During the call

  • SIP Trunking & Programmable Voice — Connect via Elastic SIP Trunking or Programmable Voice webhooks, giving you full control over call routing, recording, and real-time media streams.
  • Warm Transfers — Hand off calls to human agents or external numbers using Twilio’s conferencing and SIP capabilities, with full context passed to the next person in the conversation.
  • Real-Time Media Streams — Access raw audio streams for real-time transcription, sentiment analysis, or custom processing alongside the voice agent conversation.

After the call

  • Call Recording & Storage — Leverage Twilio’s call recording infrastructure for compliance-grade recording with configurable retention and access controls.
  • Call Status Webhooks — Receive detailed call status events — initiated, ringing, answered, completed — to trigger downstream workflows in your systems.
  • SMS Follow-Up — Use Twilio Messaging to send post-call SMS confirmations, appointment reminders, or follow-up links directly from your agent’s workflow.
  • Global Number Management — Provision, configure, and manage phone numbers across 100+ countries from a single Twilio account connected to your AgentVoice deployment.
