Arabic & More Jul 24, 2015:

If the writer meant that the two people are speaking on the phone, he should say something like:

He hung up on me.

He hung up the phone. (not "my" phone)

Arabic & More Jul 24, 2015:

Grammar Note First, the sentence should say "hung up" instead of "hanged up."

Second, where are the two people located? Because the way the sentence is written seems to imply that the two people are in the same room together. One (the speaker) is on the phone with a third party, and the second person hangs up the phone (perhaps grabbing it from his hand, although not necessarily) so that the person cannot continue his conversation.

"Phone" means the actual device (the telephone) and does not mean the "call" or "phone call."
