There have been some new tools released over the past few days and I would like to put up some basic info on some of them. Here are a few new or newer voip testing tools.
VoIPER is a VoIP security testing toolkit incorporating several VoIP fuzzers and auxilliary tools to assist the auditor. It can currently generate over 200,000 SIP tests and H.323/IAX modules are in development.
SipBomber is sip-protocol testing tool for Linux originally developed by Metalink in 2003 for internal use and released later as GPL open source product.
You can find more info about Sip Rogue in the Book Hacking VoIP Exposed.
These tools can be found in the newest version of Back|Track.
