'I'd call you up' is from the phrasal verb, to call up. Phrasal verbs are a bit tricky. it's when two words put together have a different meaning to when they are separate.. Example, 'kick off' means to start something not the literal meaning.

They are both correct and they mean the same thing. The first one is used more often.
