Once you have generated a hardware ID and submitted it to Clearly IP support team we will send you back a License File in the support ticket. You will need to follow this wiki to upload your license file in FreePBX.
Review this wiki on how to generate a Hardware ID and email it to supportcenter@clearlyip.com requesting your license. In the email make sure you reference your Invoice Number or Sales Order number from your purchase of the module.
Copy the contents of the license file the support team sent you.
SSH to your PBX and issue the following commands.
mkdir /etc/clearlyip/
cd /etc/clearlyip/
nano codex.lic
