# Fritzbox SIP Setup

> Connect a Fritzbox PBX or router-based SIP setup to itellicoAI

Use this guide when calls enter through a Fritzbox and you want to forward them into itellicoAI.

<Steps>
  <Step title="Enable SIP trunk on your Fritzbox">
    1. Open your Fritzbox admin panel (typically `http://fritz.box`)
    2. Go to **Telefonie → Eigene Rufnummern → Neue Rufnummer**
    3. Select **Andere Anbieter** as the type
    4. Enter the itellicoAI SIP endpoint (`sip:50ebbp4vhpr.eu.sip.livekit.cloud`) as the registrar
    5. Configure the SIP credentials
    6. If your firewall sits in front of the Fritzbox, allow inbound SIP traffic from the [static IP ranges itellicoAI uses](/launch/sip-trunks#static-sip-ip-ranges) (`143.223.88.0/21`, `161.115.160.0/19`)
  </Step>

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

    * **Name:** Fritzbox
    * **Termination URI:** Your Fritzbox public IP or DynDNS address
    * **SIP Auth Username/Password:** Credentials configured in the Fritzbox
    * **Allowed IPs:** Your Fritzbox public IP address
  </Step>

  <Step title="Configure call routing">
    In your Fritzbox, set up call forwarding rules to route specific numbers to the itellicoAI SIP endpoint (`sip:50ebbp4vhpr.eu.sip.livekit.cloud`).
  </Step>
</Steps>

<Note>
  Fritzbox connections require a static IP or DynDNS address. If your ISP assigns dynamic IPs, set up a DynDNS service first.
