To enable the Internet telephone function, the Gigaset M34 USB comes with the respective software from Skype. Just connect the Gigaset M34 USB to your computer. It will pass the telephone signals from the Internet on to your Gigaset S645, Gigaset S440/445 or Gigaset C340/345. So you can make calls with your Gigaset S44 or Gigaset C34 handset instead of a headset and enjoy perfect quality of service.
How cool is that?
