# Telnyx SIP Setup

> Connect Telnyx SIP Connections to itellicoAI

Use this guide when your phone numbers or trunking already run through Telnyx.

<Steps>
  <Step title="Get your Telnyx SIP credentials">
    1. Log in to the [Telnyx Portal](https://portal.telnyx.com)
    2. Go to **SIP Trunking → SIP Connections**
    3. Create a new SIP connection
    4. Note the **SIP Connection URI** and **Outbound Voice Profile**
    5. Under **Authentication**, set up 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:** Telnyx
    * **Termination URI:** Your Telnyx SIP connection URI
    * **SIP Auth Username/Password:** Your Telnyx credentials (if using credential auth)
    * **Allowed IPs:** Telnyx signaling IPs (if using IP auth)
  </Step>

  <Step title="Import and route">
    Import your Telnyx numbers and assign routing as described in [SIP Trunks](/launch/sip-trunks).
