It's just a matter of time before a large number of VoIP systems will be exploited by hackers and spammers.
"There's been a lack of security in the design and deployment of VoIP, and buyers aren't taking security concerns into consideration," Thatcher said.
Thatcher's points were accentuated by Andrew Graydon, vice president of technology at security firm BorderWare Technologies. Graydon pointed to suchimpending phenomena as Vbombing, where thousands of voice mails couldbe instantaneously left on a single VoIP console.
Ominously,Graydon added that script for attacks on VoIP systems is already available on hacker sites.
