Nice design, convenient, cheap but after installing some disappointments ... 5 rings, all stun and far from discreet ... The base is not very stable, and finally no speaker on Versatis F200 but the F250 which is not expressly stated in the announcement. When testing for the line we realized that the phone rang after 2 tone of the caller and continued to ring 5-10 sec. after the caller hung up. I rather regret my purchase, I will have seen before I would have not commanded.
