Next-Gen Agentic Voice AI.AI voice agents built on Twilio and OpenAI

Transform your customer relations. By bridging Twilio's powerful communication backbone with OpenAI's LLMs, we deploy autonomous Voice Agents and SMS bots that reason, decide, and act in real-time.

What is an AI voice agent?

An AI voice agent answers or places phone calls through Twilio, streams the caller's audio to a speech-capable AI model such as OpenAI's realtime models, and replies in a natural voice. It can look up information and take actions during the call, like booking an appointment, qualifying a lead or updating your CRM, and hands the call to a person when needed.

Infrastructure Design

Twilio x OpenAI

We engineer scalable logic streams that instantly catch inbound Twilio voice calls or SMS, route them through a high-bandwidth WebSocket into a localized Agentic AI orchestration layer, and pipe the semantic payload into OpenAI. The result? A perfectly natural, synthetic voice dynamically holding a conversation with your customer.

Frequently Asked Questions

How does an AI voice agent connect to Twilio?

Twilio answers the call and streams the audio over a WebSocket (Twilio Media Streams) to a server that relays it to the AI model. The model's spoken reply is streamed back into the call, and the server runs any tools the agent needs, such as calendar or CRM lookups.

Can the AI voice agent book appointments and update my CRM?

Yes. The agent can check availability in Google Calendar or Calendly, book the slot, send an SMS confirmation and create or update the contact in your CRM, all during the call.

Can the AI agent transfer a call to a person?

Yes. When a caller asks for a human or the conversation needs one, the agent can transfer the call to a phone number or queue, optionally passing along a summary of the conversation.

Are outbound AI phone calls legal?

Outbound AI calls are regulated. In February 2024 the FCC confirmed that AI-generated voices count as artificial voices under the TCPA, so you need the person's prior express consent before calling. Inbound call answering does not carry that requirement. Get legal advice for your specific use case.
