The paper describes the approach and preliminary results from the research project EUX2010SEC. The project works closely with Voice over IP (VoIP) companies and users. The project aims at providing better security of open source VoIP installations. The paper towards this goal is organized by gathering researchers and practitioners around scientific activities that range from security modeling and verification up to testbed testing. The expected outcomes of the project are a solid scientific and practical understanding of the security options for setting up VoIP infrastructures, particular guidance on secure, typical setups of such infrastructure.
