Telephony Security Diagnostics
Diagnostics / Security
The security diagnostics of the FRITZ!Box checks the "Telephony" area for features and functions of your FRITZ!Box's DECT base station, settings for call handling, both with the FRITZ!Box directly or via IP telephones connected via a FRITZ!App, and the activity of the CAPIoverTCP function.

Fax
What is CAPIover TCP?
CAPIoverTCP is a CAPI driver. CAPI drivers install virtual modem drivers so that analog services like faxing can be also be used digitally. With CAPIoverTCP and the "FRITZ!Fax for FRITZ!Box" software the FRITZ!Box can be used to send and receive faxes.
We recommend using the internal fax function of the FRITZ!Box for sending and receiving faxes. For more information, read the instructions Configuring the Fax Function and Sending a Fax.
