A phone call is a conversation between two or more people using a telephone. It allows individuals to communicate in real-time, regardless of their physical location. Phone calls can be made using landline phones or mobile devices, and they can connect people across short or long distances. During a phone call, participants can hear each other's voices, which helps convey emotions and intentions more clearly than text-based communication. Phone calls can be initiated by dialing a number, and they may involve various features such as call waiting, voicemail, and conference calling, enhancing the overall communication experience.
