Using Jitsi in my product

Sorry for my english.
Hello, I have a couple of questions about using the Jitsi software.

  1. Can I use it commercially? Take money for installing Jitsi on servers.
  2. I have developed my mobile application using the Jitsi SDK, as well as a WEB conference control panel. Can I get copyright for my application and WEB panel (Exactly my code). And can I sell them?

Yes.

Yep, as long it is using your deployments and not meet.jit.si this is fine.
