#16 Issue when visitor browses away from chat screen

[Amit Chatterjee]

We have a popup message when the visitor navigates away from the chat page - something to the
effect that all chat sessions will be dropped if they move away. The visitor gets this after making
an outbound call that gets rejected. The visitor gets the message that the called was busy or did not answer
and then when they move away from that (unconnected conversation) page, they get the popup (shouldn't).
