I am satisfied with the design of this product. By cons, what is missing is the silence the ringer on the phones. If someone could point me in what way we can get to perform this silence, I thank in advance. My eyesight is very bad and the leaflet accompanying this product is written in small print. What I do not understand is the reduction that I had to get for the purchase of this duo. Is Amazon or Gigaset providing this reduction? Thank you in advance for answering. If I misunderstood by buying this pair, let me know.
