Careful with that call

VoIPshield Systems recently released the results of vulnerability research on the most widely used voice-over-IP systems. Researchers found more than 100 design or implementation flaws in products from Avaya, Nortel Networks and Cisco Systems that could allow outsiders to execute code on handsets, PCs or servers; compromise systems; block service; or steal accounts.

The results have been published as 44 discreet vulnerabilities at www.voipshield.com/research. VoIPshield has worked with the vendors to find fixes for the problems and is incorporating the information into its VOIP vulnerability analysis tool and intrusion-prevention system.
