Traffic considerations for security services in VoIP systems [chapter]

Wilhelm Wimmreuter
2000 Telecommunication Network Intelligence  
Voice over IP systems require a new infrastructure of security services. The demand is currently growing and deploys basic-authentication in the first step.  ...  Additionally, if carefully implemented, they can serve for other applications besides VoiP as well.  ...  Out of the major areas of security in VoIP systems, we focus on services for user-authentication.  ...

Deployment of VoIP Technology: QoS Concerns [article]

Amor Lazzez, Thabet Slimani
2013 arXiv   pre-print
VoIP allows significant benefits for customers and service providers including cost savings, phone and service portability, mobility, and the integration with other applications.  ...  Nevertheless, the deployment of the VoIP technology encounters many challenges such as interoperability issues, security issues, and QoS concerns.  ...  Security issues: In the legacy phone system, the main security issue is the interception of conversations that require physical access to phone lines. In VoIP security issues are much more than that.  ...
