VoIP Hopper v2.01 Released

VoIP Hopper is a GPLv3 licensed security tool, written in C, that rapidly runs a VLAN Hop into the Voice VLAN on specific ethernet switches. VoIP Hopper does this by mimicking the behavior of an IP Phone, in Cisco, Avaya, and Nortel environments.

Changelog v2.01

  • Updated README file documentation.
  • Fixed a few typos in main.c, with the printing of “Device ID” (-E, not -D).  Thanks to Vladimir Kot for catching this Tue, 2/8/11.
  • New “Assessment” mode:  Interactive, menu driven command interface, improves ability to VLAN Hop in Pentesting when the security tester is working against an unknown network infrastructure.
  • New VLAN Discovery methods (802.1q ARP, LLDP-MED).
  • LLDP-MED spoofing and sniffing support.
  • Can bypass VoIP VLAN subnets that have DHCP disabled, and spoof the IP address and MAC address of a phone by setting a static IP.


  • libpcap
  • c compiler
  • Linux OS
