Crescendo telephone ringers and methods of providing a crescendo telephone ring signal. The crescendo telephone ringer provides a gradual increase in audible ringing volume as a sequence of incoming electrical ring signals is detected. According to one embodiment, upon receipt of an incoming call, a first audible ring signal corresponding to a first detected electrical ring signal is set to a minimum volume. Subsequent audible ring signals corresponding to subsequent detected electrical ring signals are set to increasing volume levels, and finally to a maximum ringer volume.
