Telephoning is going digital: almost all connections are now IP-based, so most people are already making calls over the internet. This offers many advantages, such as excellent HD sound quality, the ability to connect to three phone numbers simultaneously and to make several calls at the same time. You can enjoy all these functions with the universal Gigaset HX cordless handsets. As they are compatible with all DECT/CAT-iq-capable routers such as FRITZ!Box or Telekom Speedport, they are incredibly versatile - so you can continue to use them even if you change your router.
