5 Disabling "DECT Eco"
1. Click "DECT" in the FRITZ!Box user interface.
2. Click "Base Station" in the "DECT" menu.
3. Disable the option "DECT Eco" in the "Radio Field Strength" section.

If the telephone rings now, the DECT connection to the telephone was disturbed. Any devices that emit
radio waves could be a source of interference. These include other DECT base stations, baby monitors,
mobile telephones, and television antennas, for example. If the telephone does not receive the "wake up"
signal from the FRITZ!Box in time and therefore does not wake up from standby mode, repositioning the
telephone may help.

2. Click "Telephony Devices" in the "Telephony" menu.
3. Click the (Edit) button for the respective telephone.
4. Configure the telephone so that it reacts to incoming calls to the desired telephone number: Enter
the number under "Outgoing calls" or "Incoming calls", or enable the option "React to all numbers".
5. Click "OK" to save the settings.

Calls to your internet telephone number can only reach the FRITZ!Box if an internet connection is active.
Some FRITZ!Box models must be configured to permanently maintain the internet connection:
