The Department of Homeland Security Science and Technology Directorate understands that Broadband Push-to-Talk (PTT) services are now offered by a diverse group of vendors. and that agencies may utilize different PTT services which can result in obstacles to interoperable communications. In 2022, DHS S&T published a solicitation to research the effort to develop a broadband PTT interface solution that will provide a method to combine these diverse communication platforms while maintaining critical meta data that is needed to ensure that first responders maintain interoperable communications during critical incidents and planned events. DHS awarded four recipients and one, Catalyst Communications Technologies, was awarded a Phase II grant to develop a prototype.
