If we don't pick up a call,it just ends. So can "hang up" be used in this sense? I mean it's used with people.
Mom: Hey! I thought my phone was ringing.
I: It was but it just hung up.(no one picked it up and it ended like any call if no one picks it up.)
I guess the use of "hang up" isn't natural. So what will be actually be used in this context?
