Phone calls that are routed through the Internet instead of telephone wires are increasingly popular with businesses looking to cut telephony costs. But they have security problems that might leave a business that uses this technology vulnerable to a hacker. The extent of the problems – and the process for identifying and fixing them – is murky, however.
VoIPshield, which makes security software for these calls – the “VoIP” stands for voice over Internet protocol, the technical name for Internet telephony – will publicly announce over 100 security vulnerabilities in the VoIP systems sold by Avaya, Cisco and Nortel later today. The goal is to raise awareness about flaws in these systems – and create a market for VoIPshield’s product, Rick Dalmazzi, the company’s CEO, tells the Business Technology Blog.
