If you have an iPhone, there are a few ways to determine who ended the call. One way is to check the call logs. If you see a call that was not answered or disconnected by the person on the other end, then it’s likely that the call was cut off because they did not answer or disconnect. Another way to determine who ended the call is to use the phone’s address book. If you see a name that you know is associated with a phone number or account, then it’s likely that the person on the other end was calling from that number or account.
