Twilio Integration for AI Voice Agents + Phone Call Automation

We connect your AgentVoice voice agents to Twilio for telephony, with number provisioning, SIP trunking, and programmable voice.

Twilio telephony for your voice agents

We connect your AgentVoice voice agents to Twilio through Programmable Voice or Elastic SIP Trunking, so the agent answers and places calls over your Twilio account. Bring your own Twilio numbers, port existing numbers, or provision new ones, and we connect them to AI voice agents that handle calls from the moment they ring. If your agent places outbound calls, registered caller ID and steady calling patterns help keep your numbers off spam lists.

Twilio handles the telephony layer, including PSTN connectivity, number provisioning, and call recording. AgentVoice handles the conversation. Together, you get AI-powered call handling on your own Twilio account without touching a PBX.

What your agent can do

During the call

  • SIP Trunking & Programmable Voice. Connect through Elastic SIP Trunking or Programmable Voice webhooks for 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. Use Twilio's call recording, with access controls set on your Twilio account.
  • Call Status Webhooks. Receive call status events, such as initiated, ringing, answered, and 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.
  • Number Management. Provision, configure, and manage phone numbers from the Twilio account connected to your AgentVoice deployment.

Use Cases

Outbound Campaign Calling
