After finishing Vulnix I decided to take on VulnVoIP and try my hand with some phone system hacking! 🙂
The VM has some instructions on what to do other then get root:
VulnVoIP is based on a relatively old AsteriskNOW distribution and has a number of weaknesses. The aim is to locate VoIP users, crack their passwords and gain access to the Support account voicemail.
