Why Use HTTPS with LQ Series Units?
When using the LQ Core Configuration Manager (CCM) to establish your intercom setup, you might wish to protect your login credentials and configuration details from unauthorized interference. In this case you will establish an encrypted connection between the CCM and the LQ devices using HTTPS.
The LQ units use port 80 (http) and port 443 (https) for management. Once a Link-Group is established, audio travels in an encrypted channel between units via port 655. However, the management ports will continue to exchange configuration information once the audio channel is established, and you might want to ensure that this information travels on a secured route.
