A quick post to refer to the live bootable CD from Viperlabs called VIPER VAST. It's a Linux distribution that includes a good number of tools that can help in a VoIP security assessment. I think I'll be giving this a try next time around. What makes this useful is if you want to quickly have a machine with all the right libraries, drivers and packages installed to be able to run tools such as UCsniff. As for SIPVicious, it doesn't really have many requirements, just python. One can just run SIPVicious on most out of the box Linux and OSX. On windows one would need a python installation such as Activestate's distribution. However I am pleased to see SIPVicious being included. Congratulations to the Viper labs team for this new distro!
