Suppliers and consultants have reacted to criticism of the security of voice over IP technology by forming a group - the VoIP Security Alliance - to address user concerns.
Members include 3Com, Alcatel, Avaya, Ernst & Young's Giuliani Advanced Security Centre, Qualys, Siemens, Spirent, Symantec, the Sans Institute and TippingPoint.
The groups warn that low-cost telecoms technology, based on converged voice and data networks may not be mature enough to use on the public internet, particularly for communicating with teleworkers and business partners.
Speaking at a conference in London in February, Paul Simmonds, director of global information security at chemical firm ICI, expressed concerns that the protocols used were only viable within a secure intranet.
"VoIP is not fit for purpose. Companies need a strong corporate solution that works outside the traditional network perimeter," he warned.
Brian Kelly, director of the Giuliani Advanced Security Center at Ernst & Young, added, "Despite the advantages of VoIP, if the technology is not implemented properly and securely, it can circumvent existing security controls and expose our networks."
