RFI for DISA D-ESInet system

The Defense Information Systems Agency (DISA) has issued a Request for Information (RFI) seeking industry input on the design, implementation, testing, operation, and sustainment of a Department of Defense Emergency Services Internet Protocol Network (D-ESInet). This specialized network aims to provide a secure, reliable, and interoperable infrastructure for routing emergency calls to the appropriate DoD Public Safety Answering Points (PSAPs). The RFI is focused on developing a system that can efficiently handle emergency communications across both Continental United States (CONUS) and Outside Continental United States (OCONUS) locations. DISA is looking to enhance its emergency services communication capabilities by creating a robust, technologically advanced network that meets the complex needs of the DoD emergency services community. The RFI represents a critical step in modernizing emergency communication infrastructure for military installations and personnel.

Contractors interested in this opportunity must submit a concise three-page capabilities statement demonstrating their ability to support the D-ESInet system by March 28, 2025, at 2:00 PM EST. The RFI requires potential vendors to address several key technical requirements, including support for multimedia emergency calls, SIP Connect 2.0 protocol, Transport Layer Security, and compatibility with XML data structures. Eligible contractors should be prepared to provide information on their technical approach, security implementations, disaster recovery plans, and a Rough Order of Magnitude (ROM) pricing for both CONUS and OCONUS phases. The system must comply with DoD Security Technical Implementation Guides (STIGs), Security Requirements Guide (SRG), and FIPS 140 requirements. While there is no specific set-aside for this opportunity, DISA is seeking comprehensive solutions that can handle up to 2.5 million numbers across 8 infrastructure instantiations, with call ingress limited to DoD VoIP assets connected to NIPRNet. The ultimate goal is to develop a secure, reliable network that can effectively route emergency calls and support the DoD's emergency services communication needs.
