Why each option
ToneLoc and THC-Scan are dedicated war dialing tools that automatically dial large ranges of telephone numbers to identify modems and remote access systems.
Wingate is a proxy server and internet gateway application used to share internet connections, not a tool for scanning telephone numbers.
ToneLoc is a classic DOS-based war dialing utility that sequentially dials telephone numbers and logs which numbers answer with modem tones, enabling attackers to locate vulnerable dial-up targets.
THC-Scan (by The Hacker's Choice) is a more advanced war dialer that can detect carrier tones, PBX systems, and voicemail boxes across large phone number ranges, making it a direct tool for war dialing attacks.
NetStumbler is a wireless LAN discovery tool (used in war driving) that detects 802.11 Wi-Fi networks, not a telephone-based war dialing utility.
