"Hangs up on" is a common phrase used to describe the abrupt disconnection of a phone call or any communication medium. However, there are numerous synonyms that can be used to describe the same behavior, including disconnect, drop, cut off, end, terminate, break off, discontinue, and cease. People can also use idioms like 'slam the phone,' 'give someone the cold shoulder,' or 'ghosting,' which refer to avoiding or ignoring someone purposely. Regardless of the word or phrase used, hanging up on someone is a rude behavior and should be avoided. It can negatively impact relationships, both personal and professional, and reflects poorly on the person who engages in it.
