“Abgelehnter Anruf” is a German phrase that interprets to “rejected name” in English. It refers to a telephone name that was not answered or was intentionally ignored by the recipient. Missed calls could be irritating for the caller, however they can be an indication that the recipient is busy, unavailable, or bored with speaking.
There are various explanation why somebody would possibly reject a name. They could be in a gathering, driving, or just not within the temper to speak. In some circumstances, a rejected name could also be an indication that the recipient is avoiding the caller. You probably have repeatedly referred to as somebody and so they haven’t answered, it’s best to respect their needs and cease calling.
