You can block any specified number, as well as any head string of 2 to 8 digits matching your specified numbers. The feature helps to reduce unwanted calls such as toll-free calls & helps to keep your personal time from being interrupted. Any number added on one handset will automatically go to the base unit & can be shared with every extra handset registered to the base unit (up to 50 entries). The handset matches your interior through its gentle, rounded form. The compact base unit is designed with an elegant wedge-sole silhouette in mind so that it does not disrupt the relaxing atmosphere of your sophisticated interior. The base unit's large cradle (handset receptor) makes it easy to pick up & put the handset back smoothly. Self-standing handset lets you see the display easily when a call is received (even during non-charging), as well as ensuring that you can clearly hear other party's voice from the speakerphone.
