Other Reasons For Silent Calls
People using telecommunications devices for the deaf (TDDs) and calling public agencies might expect the agency being called to answer with a TTY. The caller waits for "TTY tones" to be generated over the phone line. The answerer should place the phone receiver into the TTY coupler and type anything ("Hello, Go Ahead") so the caller knows it is connected. For public agencies that have a TTY, it is inappropriate to hang up on a silent call.
Many silent calls are a result of process known as pinging. This is very similar to an Internet Protocol (IP) ping, where the intention is to see if there is life at the destination. This is often used by data cleaning companies as a method of removing dead telephone numbers from old lists. Each number is dialed and immediately dropped if the call is connected. If the call is not dropped quickly enough it may result in a short ringing signal.

Famous quotes containing the words reasons, silent and/or calls:
“Here we also see: what this divinity lacks is not only a sense of shame—and there are also other reasons for conjecturing that in several respects all of the gods could learn from us humans. We humans are—more humane.”
—Friedrich Nietzsche (1844–1900)
“They mustn’t know my despair, I can’t let them see the wounds which they have caused, I couldn’t bear their sympathy and their kind-hearted jokes, it would only make me want to scream all the more. If I talk, everyone thinks I’m showing off; when I’m silent they think I’m ridiculous; rude if I answer, sly if I get a good idea, lazy if I’m tired, selfish if I eat a mouthful more than I should, stupid, cowardly, crafty, etc. etc.”
—Anne Frank (1929–1945)
“For morality life is a war, and the service of the highest is a sort of cosmic patriotism which also calls for volunteers.”
—William James (1842–1910)
