call up

Other day, I read something that called my attention:

-"Dean has to wake up early every day to CALL UP his brother, or else he oversleeps and misses work">

- Does to "call up" exist (meaning "To wake sb up? )?
I haven´t found it anywhere. (I know the other definitions, such as: to order someone to join the army, navy, or airforce ; to telephone someone).

In this case, "call up" means to telephone him. :wink:
