You have the choice of whether to make calls directly via the handset or in hands-free mode. This gives you the freedom to multitask while talking, and other people can also listen and speak. You can also select which of the two hands-free profiles you prefer. Adjust the emphasis of higher or lower frequencies to suit your comfort. No matter how you choose to communicate, you can rely on perfect sound quality. If you don't want to take calls, you can ignore specific phone numbers or anonymous callers. When the call block list is activated, calls from up to 32 numbers included in it will not be signaled or will only be displayed. You can manually add unwanted phone numbers to the block list or transfer them from the call log. You can also avoid ringing from anonymous calls without caller ID and additionally set a schedule to determine when the handset should ring and when it should not.
