VoIP Over IP Security Alliance (VOIPSA) is a cross-industry coalition of individuals and organizations from the security and VoIP communications sectors that work to raise awareness and address current security threats to VoIP technology.
The Voice Over IP Security Alliance was founded in 2005 as an open, nonprofit, vendor-neutral organization whose mission is to promote the current state of VoIP security research, VoIP security education and awareness, and free VoIP testing methodologies and tools.
