Our old phone was also replaced as part of a new Fritz box 7490. The connection and integration took 3 minutes. The voice quality is very good, ringtones and volume are very well adjusted. You can tell just when we are using the phone on the terrace. Here it is W-LAN bad and we have to go for the listener `s house. This is but no problem. I does not have to notify the neighborhood when I call and what is at stake because!
