Product Specifications

The Gigaset M34 USB is a small, easy-to-use USB adapter for computers. It offers you an incredible array of options. Calls on the internet (Voice over IP) reduce your costs. Messenger services are equally possible. Thanks to the internet alert function, you can see which of your friends are online and when. Naturally, the Gigaset M34 USB also functions like a conventional ISDN radio adapter, which provides computer connection to the ISDN base station for cordless Internet surfing. 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.
