The Voice Over IP Security Alliance (VOIPSA) was an industry group focused on promoting security awareness and best practices within the realm of Voice over Internet Protocol (VoIP) and unified communications (UC). Its primary objective was to address security challenges related to VoIP technology and to provide resources and guidance for securing VoIP deployments.

VOIPSA was founded in 2005 and consisted of various professionals, researchers, and organizations with expertise in VoIP, networking, and security. The alliance aimed to foster collaboration, knowledge sharing, and the development of security solutions to protect VoIP and UC systems from threats and vulnerabilities.

Key activities and goals of VOIPSA included:

1. Security Research and Information: VOIPSA members contributed to research and analysis of security vulnerabilities, threats, and emerging risks in VoIP and UC environments. The alliance shared this information with the community to raise awareness and promote proactive security measures.
2. Best Practices and Guidelines: VOIPSA developed and promoted best practices, guidelines, and recommendations for securing VoIP deployments. This included guidance on protecting VoIP infrastructure, endpoints, and network connections.
3. Education and Awareness: The alliance conducted educational initiatives, including webinars, conferences, and workshops, to educate professionals about VoIP security challenges and solutions.
4. Industry Collaboration: VOIPSA facilitated collaboration between security professionals, vendors, researchers, and organizations to collectively address security concerns and improve the overall security posture of VoIP systems.
5. Resource Sharing: VOIPSA provided resources such as whitepapers, tools, and research findings to help individuals and organizations understand and mitigate VoIP security risks.

It’s important to note that as of my last knowledge update in September 2021, VOIPSA’s activities have largely tapered off, and its website and initiatives may not be as active as they once were. However, the need for securing VoIP and UC systems remains relevant, as these technologies continue to be widely used for voice communication and collaboration.

As with any technology domain, staying informed about the latest security trends and best practices for VoIP is crucial to maintaining the integrity and confidentiality of communication systems. Organizations and individuals should refer to reputable sources and industry organizations for guidance on securing their VoIP deployments.
