Hello. I want to save my own VoIP phone calls and listen in part. So far I could do a packet recording over a Fritz box (rout). Unfortunately, this feature has been dropped. It depends on a PC in the network, which is connected via the Fritzbox to the Internet. Wireshark is installed - but I have massive problems with it.
How can I save (either with Wireshark or without - that does not matter) the telephone calls which are led over the Fritz box?
