# Connect via SIP Trunking with Telnyx

> Guide to integrate Telnyx phone numbers with SigmaMind using SIP trunking.

If you own phone numbers in **Telnyx**, you can connect them to **SigmaMind** using Elastic SIP Trunking.

This guide will walk you through creating a SIP trunk in Telnyx and linking it with **SigmaMind**.

## Steps to Integrate

1. **Log in to Telnyx Portal** → [Telnyx SIP Trunking](https://portal.telnyx.com/#/voice/connections).

2. **Create a New Connection**
   * Go to **Real-Time Communications -> Voice -> SIP Trunking**.

   * Click on **Create SIP Connection**.

   * Select **FQDN** as the connection type.

   * Name it (e.g., *SigmaMind SIP Trunk*).

3. **Add FQDN**
   * In the **FQDN** field, enter:
     ```
     5t4n6j0wnrl.sip.livekit.cloud
     ```
   * Set the **Port** to `5060`.
   * Choose the **Transport Protocol** (UDP, TCP, or TLS).
   * Enable **SIP over TLS** if using TLS.

4. **Assign Numbers**
   * Attach your purchased Telnyx number(s) to this connection.

5. **Termination URI**
   * Use the **Termination URI** provided by Telnyx.

6. **Transport & Encryption**
   * Allowed Transports: UDP, TCP, TLS.
   * Media Encryption: Enable **SRTP**.

7. **Save and Test**
   * Save your configuration.
   * Place a test call to confirm SIP trunking works.

## Verification

* Ensure the number is visible in your **SigmaMind Dashboard**.
* Assign an **Inbound Agent** to receive calls on this number.

<Note>
  Telnyx offers advanced SIP features such as **mutual TLS** and **static IP auth**.
  Since SigmaMind does not currently support static IP whitelisting, use **SIP URI with SRTP** for connectivity.
