Internet Telephony has Security problems

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.
