with Cody calling him

[lagoo]

Hi, I came across the sentence below in a news report on the Mirror website:

‘Mr Hankin said: "A similar pattern ensued the next day with Cody calling him repeatedly and him not picking up.”’

I have two questions regarding the “with” clause.

1. If “calling” and “picking up” are gerunds, could I replace “Cody” with “Cody’s” and “him” with “his”?
2. If those above-mentioned verbs are participles, why is “him” used here instead of “he”?

Your prompt response would be highly appreciated.

1. Yes, grammatically you could but there's no need to.
2. It's not correct to say he not picking up.
