Video Chat in Action

To test your video chat setup, you need to create a video chat session. Have a look in the video chat section of the user guide in order to see how that works.

Video Chat Limitations

  • If the visitor navigates to a new page inside the Unblu instrumented web page the video connection will be disrupted during the page load and will automatically re-establish a connection as soon as possible. To overcome this problem the visitor can use the Popout Feature.

  • The video chat can only be displayed in one window / tab. If the visitor has several tabs / windows open that belong to the same Unblu Conversation, the video chat will stay in one window. If the user wants to transfer the video chat to a different window he can do this in the chat user interface.

  • Currently, only 2 concurrent video chat participants are supported.
