The Siemens Gigaset M34 USB is an adapter that will allow an existing Siemens Gigaset telephone to work with your computer and make VOIP call. This means that when you make a call instead of the connection being made through your standard telephone line the call is made over the internet which often works out much cheaper.
Siemens Gigaset Compatibility
There are a number of Siemens Gigaset telephones that are compatible with the Siemens Gigaset M34 USB VOIP adapter. These are as follows:
Siemens Gigaset C340/345
Siemens Gigaset S440/445
Siemens Gigaset S645
Siemens Gigaset SL440
Siemens Gigaset S450/S455

To install the Siemens M34 USB comes with a CD with Skype which has to be installed for it to function. If the downloaded version from the internet is installed that will need to be removed first as the M34 does not work with that version.
