- emilis_info 18y agoThanks for the link. The Zfone FAQ page mentions, that Skype uses VBR codec for audio which is insecure: "Johns Hopkins University researchers have observed that when voice is compressed with a variable bit-rate (VBR) codec, the packet lengths vary depending on the types of sounds being compressed. This leaks a lot of information about the content even if the packets are encrypted, regardless of what encryption protocol is used. We strongly recommend that you avoid using VBR codecs if you want to make a secure phone call. <...> ...This means that Skype is vulnerable to VBR leakage regardless of the quality of Skype's built-in crypto."
