I have the ringer on my LG231 set to "telephone" but it does not ring.

A woman's voice says "Call from ........" It only repeats once and then terminates the call. When the call is terminated then it will ding to let me know. By then it is too late. It is impossible to receive and answer a call. I have read the manual and gone through all the menu items. I have volume up to the top, and ringer set. I cannot find a way to change this.
