Privacy settings: call block and call barring
Value your privacy and quiet time at home? Black List restricts specific numbers or those starting with certain digits, protecting you from receiving unwanted calls. You can choose to block up to 4 sets of numbers. Each set can consist of 1 to 24 digits. If the number of an incoming call starts with any of these number sets or are the exact numbers that you choose to block, your phone will not ring. With Call Barring, you can avoid the surprise of expensive phone bills by blocking calls from specific numbers starting with certain digits (for example, pay per call numbers).
Advanced sound testing and tuning for superb voice quality
We test the sound quality of our DECT phones the same way as high-end headphone manufacturers do. Using an advanced ear simulator, we can accurately re-create the way people actually hear. This helps our acoustic engineers to measure and fine-tune things like frequency response, distortion and overall hearing perception, to create perfect voice reproduction.
