Companies struggle with VoIP security
Equipment interoperability problems and confusion over who is responsible for security are to blame for the lack of security in voice over IP, an issue that’s a major concern for IT administrators, said experts speaking at VON Europe on Wednesday. The technology and standards for securing VoIP are not the issue, said Tim Jasionowski, senior technologist for voice and rich media technologies at Nokia Corp. The problem is that most companies aren’t using many of the technologies. That’s mainly because unless a company uses a single vendor for every piece of equipment in the network, including phones, IP-PBXs, firewalls and all other components in between, then security technologies such as Transport Layer Security (TLS) are unlikely to run smoothly across multivendor equipment, he said.
