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
