UNSPSC 43221518: Telephony equipment toll restrictors

Equipment inserted in an outgoing dial trunk that restricts calls to forbidden or unauthorized codes.

UNSPSC 43221518 Telephony equipment toll restrictors is a Commodity code that in recent state and local practice captures software and systems-integration work for voice communications infrastructure modernization, particularly cloud-based telephony and computer-aided dispatch platforms rather than discrete hardware devices. State and local issuing bodies soliciting under this code include municipal governments and law enforcement agencies seeking end-to-end voice systems overhauls. The City of Conroe, Texas, for example, posted an RFP in April 2026 for a managed VoIP telephony system to replace on-premise Mitel infrastructure across 40 municipal locations, seeking proposals for cloud telephony with Microsoft Teams Phone integration, hardware provisioning, call recording, and managed support services. The Michigan State Police posted an RFP in October 2026 for a Software-as-a-Service Computer Aided Dispatch solution. Both solicitations reflect a shift from point-product procurement toward integrated platform and services delivery models that bundle telephony capabilities with operational software, infrastructure migration, and vendor-managed support.

Activity under this code concentrates in Texas and Michigan, with the most recent opportunities concentrated in the second and fourth quarters of 2026. The City of Conroe RFP (due May 21, 2026) required SOC 2 Type II or ISO 27001 certification, compliance with CJIS and HIPAA standards, $1,000,000 public liability coverage, and a 120-day firm pricing commitment; vendors could bid on either Install & Migration or Support Services categories or both, with a one-year initial term and four one-year renewal options. The Michigan State Police RFP (due November 12, 2026) sought CAD capabilities addressing operational workflows, configurability, technical architecture, security, and implementation models. The Harlingen Consolidated Independent School District in Texas also posted related automation and systems integration consulting services in May 2026, though the scope of that procurement diverges from core telephony work. No contract values or set-aside designations were disclosed in the published summaries.
