Limited Sources Justification_Direct SIP_redacted.pdf

This is a Justification Review Document for a sole source procurement by the National Guard Bureau for Direct SIP Trunking services. The contracting activity is 159 FW/MSC with a requiring activity of 159 FW/CS. The requirement is for Local Telecommunication Services for Session Initiated Protocol (SIP) Trunking, specifically Direct SIP Circuits for the BVOIP System, as a new contract on a firm fixed-price basis with O&M funding from the Air Force.

The justification cites 10 U.S.C. 2304(a)(1) or 41 U.S.C. 3304(a)(1) authority for limiting competition to a single responsible source. AT&T is identified as the only provider suitable to meet the requirement, as it is already established on the base with full AT&T infrastructure across all servicing locations, including routers, switches, and fiber network equipment that is exclusively controlled by AT&T and cannot be replicated or accessed by another vendor without substantial duplication of cost and service interruption. The document notes this contract is an upgrade to an existing system with only minimum changes required. A Sources Sought Notice was posted on the GPE, generating six interested parties (NT Connect Holdings, Bright Packet, Granite Telecommunications, KraiaNet, Spectrum Business, and AOC Connect), though market research determined no other vendors could provide the requirement without a complete infrastructure overhaul. The document was prepared on June 30, 2026, with contracting officer approval dated June 25, 2026.
