Security Test Environment for VoIP Research

Voice over IP (VoIP) is in wide use today, replacing phone lines in many scenarios. However, often, security isn’t considered well enough, even though many security attacks are already known. More research on VoIP security is needed to enhance the level of security of VoIP systems and to show the implications of failing to take appropriate security measures. This paper presents a short introduction in testing VoIP components, proposes an architecture and implementation of a robust, flexible and efficient VoIP test environment for security related tests. Experiences using the implemented environment for different VoIP security tests are shown to demonstrate the suitability of the proposed test environment for research and teaching purposes.
