Like Without picking up the call communicate with the caller.
See someone's status in real time while you call them.
When some one calls you they can know your status in real time which would help them to take subsequent action. Like you have set a status that says you are sleeping. That means you will not respond to their call and you are not avoding them. This is a technology which can send message even without typing.
