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.
