When using Google Chrome, you may encounter this error when navigating to client.lifesizecloud.com
Google has updated Chrome to no longer allow requests for the webcam from insecure sites (non-ssl). Which is causing this error to show up.
A workaround would be to use Internet Explorer for guest dialing from a browser.
NOTE: You can also use our new Call Me page for guest dialing, by using the link below and changing the (123456) to the extension you wish to dial. This will figure out which browser to put you on, and direct you to the right page.
