How to plan a calls?

I would like to plan calls or reacalls when after one phone I have to call to the same customer another time.

For now I can only make a task, after that cloase the task, make a call and then register it. It's a lot of operations. 

How to do iit faster and simpler? Mayby some kind of future call and reminder from a call funkcion?
