A trunk is our connection to the outside world. We use it to tell FreePBX about any call providers we use for inbound and outbound calls. You can set up as many trunks as you want.
Configuring a trunk with different providers will be similar but can vary in the exact settings used. If you’re unsure how to configure FreePBX with your provider ask them for information about configuring their service for use with Asterisk (and specifically FreePBX). If you still can’t get it to work open a support ticket and we’ll check it out.
