Do you already have a base station, but want to expand it with an extra handset? You can find our range of individual handsets to expand your current base station here. All devices have the so-called GAP functionality. Thanks to the GAP technology, you don't have to choose a handset by the same brand or product line as your base station. Keep in mind that if you choose a different brand, only the call and receive call functions are guaranteed to work. Note: These handsets are delivered separately, but don't work without a base station. If you already have a base station, connect this extra handset to it. Don't have a base station yet?
