Ram Dantu, Assistant Professor, is the Principal Investigator of a $600,000 multi-university grant from the National Science Foundation. UNT is the lead institution in collaboration with Columbia University, Purdue University, and the University of California at Davis to develop a geographically distributed, secure test bed to analyze vulnerabilities in Voice over Internet Protocol (VoIP).

The three-year project will investigate voice spam prevention, attacks on networks and Internet resources that render them unavailable, quality of service, and 911 service dependability. They have conducted two VoIP security workshops that have received support from several agencies, including the Department of Homeland Security, the Federal Communications Commission, and the National Security Agency. A third workshop is planned in June 2006 in West Berlin, Germany. More information about this grant is available from this NSF press release
