Is there way to quickly call the active contact on the Message app? Oftentimes, in the middle of texting, I find myself wanting to call the other party instead. 

However, in order to do that, I would have to scroll all the way to the top of the message history, just to get to the CALL button. 

Is there a faster way to do this? Tapping on the contact name seems to be a logical trigger, but it doesn't work.
Tap on the status bar will bring you to the top of the message. A quick way to get to the call button.
