Voice Circuit Modernization Service

The government authority located in Ada, Oklahoma is seeking a vendor to provide voice circuit modernization services. The agency is trying to solve the inefficiencies of its decentralized, legacy circuit-based architecture by transitioning to a centralized, highly available Session Initiation Protocol (SIP)-based Unified Communications environment. This modernization requires a full redesign or re-architecture of the existing Unified Communications platform. The scope of work requests the replacement of core platforms, including CUCM, CUBE, Unity, and CER. The project covers the procurement, installation, or replacement of hardware such as servers, gateways, phones, and analog devices, alongside endpoint deployment, relocation, or physical troubleshooting. Additionally, the selected vendor must handle direct coordination with telecommunications carriers or SIP providers and troubleshoot issues determined to be carrier-side or outside the agency-controlled infrastructure. The requested services also encompass WAN/LAN redesign, reconfiguration, or performance tuning, and the resolution of underlying network capacity or performance issues. The agency requires integration with non-Unified Communications applications, such as contact center platforms, paging systems, and third-party applications, unless explicitly stated otherwise. Finally, the scope includes large-scale manual data correction beyond reasonable normalization, end-user training, communications, adoption programs, ongoing monitoring, help desk support, and incident management. Only onshore organizations based in the United States are eligible to bid on this opportunity. The agency expects the performance of the work to be conducted offsite. Bidders must submit their proposals digitally via email or online, and the agency is currently looking for proposals to establish the budget. All questions regarding this procurement must be submitted no later than May 27, 2026.
