A completed call in terms of telecommunication and telephony is defined as a call initiated by the calling party which reaches the desired recipient and is answered by them. Simply put, a completed call is any call that is answered by the called party. However, some people define completed calls as the calls which either get answered or rejected but do not go unanswered. According to this school of thought, even the calls rejected by the called party due to them being busy or unavailable is also called a completed call.
