I was able without lintégrer problem in my family telephone network DECT / GAP Gigaset C530 IP. You just make sure that the base pin code is 0000. You can then change the code, once all handsets and loreillette are associated with the base. C565 This headset is lightweight and comfortable to wear. The audio quality is very good. The charging cradle is equipped with a magnet providing good electrical contact with loreillette. The day the rechargeable battery will be out Of Use, it will be easy to change as easily accessible. I do not have to reproach.
