## Permiting TTNC traffic through Sangoma Firewall The most up to date list of TTNC IPs can be found here: [How to setup VoIP destinations](doc:how-to-forward-phone-calls-to-voip) If you are using the Sangoma Firewall, place our IPs within the trusted zone so no filtering will be applied within the FreePBX control panel. This can be done by navigating to `Connectivity` → `Firewall` → `Network` You can also enable the 'Responsive Firewall' here to block repeated malicious registration attempts. *** ## Registering a User-Based SIP Trunk This is a general guide for configuring TTNC SIP trunks with FreePBX; the SIP driver used will be chan\_pjsip. UI changes may occur between different versions, but it should be possible to use this guide for any recent installations of the software. This guide is based on version 14.0.5. This guide assumes you have successfully installed FreePBX and you have the following configured: * You have configured an Administrative user * Permitted TTNC traffic through your firewall * You have created one or more extensions that are registering correctly > 🚧 Inbound Numbers > > Multiple inbound numbers are not supported on a User-Based trunk. To configure individual numbers, you will have to use an [IP authenticated trunk](doc:freepbx#section-registering-an-ip-based-sip-trunk). Navigate to `Connectivity` → `Trunks`\ Click `Add Trunk` → `Add SIP (chan_pjsip) Trunk` Under `General`, set the following:
