Use this guide when calls enter through a Fritzbox and you want to forward them into itellicoAI.
1

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 (143.223.88.0/21, 161.115.160.0/19)

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
3

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