Show mobile status as Rainbow status

Hello,

I know that this feature request has been raised before, but I want to push for it again.

There should be a choice to set the "busy" state in Rainbow if busy in mobile call (mobile client installed and active).

In our market this feature is being offered by other solutions, and it would be a great help in promoting the usage of Rainbow.
I know that this implies larger volume of data sent from client, but it would be worth it.
Dataplan is not an issue 2019, together with an choice for the user..
