The tool that may be used to directly violate the confidentiality of communications on an unencrypted VoIP network is Wireshark.

Here's why:

a. Nikto is an open-source web server scanner which performs comprehensive tests against web servers for multiple items, including potentially dangerous files/programs. It doesn't directly violate the confidentiality of communications on an unencrypted VoIP network.

b. Nmap ("Network Mapper") is a free and open-source network scanner created by Gordon Lyon. It is used to discover hosts and services on a computer network, thus building a "map" of the network. It doesn't directly violate the confidentiality of communications on an unencrypted VoIP network.

c. Wireshark is a network protocol analyzer. It lets you see what’s happening on your network at a microscopic level. It can be used to capture VoIP traffic on an unencrypted network, which can then be analyzed and replayed.
