# Twilio SIP Setup

> Connect Twilio Elastic SIP Trunking to itellicoAI

Use this guide if your phone numbers already live in Twilio and you want inbound calls to route through itellicoAI.

<Steps>
  <Step title="Get your Twilio SIP credentials">
    1. Log in to the [Twilio Console](https://console.twilio.com)
    2. Go to **Elastic SIP Trunking → Trunks**
    3. Create a new trunk or use an existing one
    4. Under **Origination**, add the itellicoAI SIP endpoint (`sip:50ebbp4vhpr.eu.sip.livekit.cloud`) as the origination URI
    5. Under **Termination**, note the termination SIP URI
    6. Under **Authentication**, create or note SIP credentials. As an additional layer, you can also allowlist the [static SIP IP ranges](/launch/sip-trunks#static-sip-ip-ranges) (`143.223.88.0/21`, `161.115.160.0/19`) — these are shared egress ranges and should complement credentials rather than replace them
  </Step>

  <Step title="Create SIP Trunk in itellicoAI">
    Go to **Telephony → SIP Trunks → Create SIP Trunk**:

    * **Name:** Twilio
    * **Termination URI:** Your Twilio termination SIP URI
    * **SIP Auth Username:** Your Twilio SIP credential username
    * **SIP Auth Password:** Your Twilio SIP credential password
  </Step>

  <Step title="Import your Twilio numbers">
    Go to **Telephony → Phone Numbers → Add Number → Connect Your Own**:

    * Enter each phone number in E.164 format
    * Select the Twilio SIP trunk
    * Assign routing to your agent
  </Step>

  <Step title="Configure Twilio forwarding">
    In the Twilio Console, configure your phone numbers to forward to the itellicoAI SIP endpoint (`sip:50ebbp4vhpr.eu.sip.livekit.cloud`).
