Configuring a FreePBX Version 13 Trunk

Intro To FreePBX v13

FreePBX is a web-based open source GUI (graphical user interface) that controls and manages Asterisk (PBX), an open source communication server. FreePBX is licensed under the GNU General Public License (GPL), an open source license. FreePBX can be installed manually or as part of the pre-configured FreePBX Distro that includes the system OS, Asterisk, FreePBX GUI and assorted dependencies.

You'll need to have created an Credential based connection^PORTAL on your Telnyx Mission Control Portal account, assigned this connection to a DID and outbound profile in order to make and receive calls.
