Voice over IP Security

Voice over IP Security VoIP refers to a class of products that enable advanced communication services over data networks. While voice is a key aspect in such products, video and other capabilities (e.g.,collaborative editing and whiteboard sharing, file sharing, calendaring) are supported. The key advantages of VoIP are flexibility and low cost. The former derives from the (generally) openarchitectures and software-based implementation, while the latter is due to new business models, equipment and network link consolidation, and ubiquitous consumer-grade broadband connectivity.
