How to open route with another protocol?

I have ember application which opens with http but I have button for videochat but WebRTC works only on page with https. So I need open route in new window and with https protocol. Can I do it with link-to? My link:

{{#link-to "videochat" model.id class="call-button" target="_blank"}}Call{{/link-to}}

Now I'm doing with window.open in controller action, but some browsers block opened window.
