The telephone facility on the FritzBox is very simple. We'll show you how to do it and other practical functions..
AVM's FritzBox is not only a popular router system for Internet and WLAN, but most versions also have a built-in telephone system. With the, users can adapt their telephony needs according to their own wishes, assign phone numbers and integrate wired and cordless telephone headsets or even fax machines. The procedure is very simple. There are basically three ways of connecting a telephone to the FritzBox: On the one hand, the classic "plug-in method", in which the telephone is simply plugged into one of the telephone connections on the FritzBox. The second method uses the FritzBox's integrated DECT station: wireless telephones - regardless of whether they are from AVM or other manufacturers - can be connected to the FritzBox without pulling the strings. The third method is to connect an app.
Of course, you can also connect a normal cable phone to the FritzBox via TAE port and then set it up like a DECT phone. All you have to be aware of is that modern Fritz boxes no longer support pulse dialing. This means that the phone must support tone dialing. This is usually the case with all push-button telephones from the past 30 years. Rotary phones do not work. Older FritzBox models such as the 7370 can also use pulse dialing, and there are (expensive) adapter solutions - but the method is anything but reliable.
