I built a Azure based platform that pulls the recordings out of FreePBX via SFTP and shoots them to Azure Blob Storage, and has a web based interface for pulling recordings, unfortunately it’s owned by my company, I don’t have IP rights :(.
Ok well if you are changing things in FreePBX they are covered by the terms of the GPL which states all the modifications have to licensed as GPL. This is not something you can decide not to follow.
We don’t actually modify FreePBX, but implement dial plans and SFTP access, to be specific.
