• Currently no built-in end-to-end encrypted traffic

  • certain protocols (SIP) have add-on encryption features
  • there has been talk of adding encryption to the IAX protocol

• VPN tunnels are possibilities

  • greatly enhance security, but incur maintainance overhead and extra lag time in conversations
    • with fast enough/in-hardware encryption equipment on both ends, it may not be noticeable

• Make sure you keep up with recent exploits and update your Asterisk server in a timely manner

  • this may require having test platforms available
