# Outbound calls with Twilio

> Using your Layercode Agent to make outbound phone calls

<Note>
  You will need:

  * A Layercode Agent with an assigned Twilio phone number (see [Inbound calls with Twilio](/how-tos/setting-up-twilio))
</Note>

This guide walks you through triggering an outbound phone call from your Layercode Agent.

To trigger an outbound call, use the [`https://api.layercode.com/v1/agents/AGENT_ID/calls/initiate_outbound` endpoint](/api-reference/rest-api#initiate-outbound-call). You can call this endpoint from your backend whenever you want to initiate a call.  You must have already set up your Layercode Agent to work with Twilio. If you haven't done that yet, see [Inbound calls with Twilio](/how-tos/setting-up-twilio).

Goto REST API docs for **[more details about calling initiate\_outbound](/api-reference/rest-api#initiate-outbound-call)**.
