A USB phone adapter is a device that allows for the direct connection of your phone to the computer so that you may access Skype and other online calls on the regular home telephone. The connection of an USB phone adapter does not impair the regular functions of your phone because you will continue to use the landlines as normally as before. A manual or automatic switch is possible for accessing the Internet calling mode, which serves for dialing purposes as well. The phone will also ring for both Internet and land calls, and you will be using the device in much the same way regardless if the signal is sent via computer or by the regular landlines.

The functionality of the USB phone adapter does not depend on very complex mechanisms. Without any further equipment, the adapter ads a new mode to the phone. The adapter can be used on any kind of phone model, and the ringing remains the same for landlines and the Internet. The power for the USB device is taken from the computer, and whether regular or cordless, the phone operation remains unchanged.

There are devices that enable auto-switching for incoming Internet calls or landline calls. The only way to make a difference between the calls is by following the LEDs that go on: there will be one for power, one for the Internet and one for landline calls. Some softwares are normally necessary to make the application possible, but these are included in the package of the USB phone adapter together with the cables and the installation manual. Although almost anyone can use the device, there are some technical requirements to be met nevertheless. It is therefore important to check the technical information before ordering the product on the Internet.

Apple applications are seldom compatible with a USB phone adapter. Windows is the most common platform for the application. Then, even the Windows platform needs to be 2000, XP or Vista. The phone switch will not work for anything below. There should be at least 128 MB RAM and 15 MB free disk space. If you can’t determine the status of your computer, ask for professional help. Last but not least, the Internet connection is also important for the USB phone adapter, as only broadband modes such as cable or DSL are acceptable.
