UNSPSC 43222805: Private branch exchange PBX equipment

A PBX (private branch exchange) is a telephone system within an enterprise that switches calls between enterprise users on local lines while allowing all users to share a certain number of external phone lines. The main purpose of a PBX is to save the cost of requiring a line for each user to the telephone company's central office. The PBX is owned and operated by the enterprise rather than the telephone company (which may be a supplier or service provider, however). Private branch exchanges used analog technology originally.

Today, PBXs use digital technology (digital signals are converted to analog for outside calls on the local loop using plain old telephone service).

UNSPSC 43222805 Private branch exchange PBX equipment (Commodity) encompasses telephony systems hardware, software licenses, maintenance, and related professional services that state and local governments acquire to maintain and expand internal communications infrastructure. State and local buyers under this code procure complete PBX platforms including Communication Manager systems, messaging platforms, group equipment, and data networking components alongside engineering support, installation, project management, and tiered maintenance coverage spanning standard business hours and 24/7 availability. The state of Washington has demonstrated sustained demand, with Washington State Technology Solutions soliciting qualified vendors through an RFQQ to establish a statewide contract for Avaya products and services covering multiple state agencies, including the Department of Social and Health Services and Department of Corrections, alongside coverage across five counties.

The RFQ posted July 16, 2026 (RFQQ 26-RFQQ-004) with response deadline August 6, 2026 illustrates current state and local procurement patterns under this code. The four-year equipment and five-year maintenance contract structure reflects the long-term, standardized purchasing model typical of statewide cooperative vehicles; the solicitation documents existing Avaya infrastructure across 14 regional sites statewide and requires vendors to meet response-time and travel-distance requirements from identified service locations. Estimated maintenance costs total $1.303 million over five years, with monthly per-license baseline rates of $30.00 for supervisor and agent licenses, while equipment purchase estimates range from $10,000 to $200,000 per category. Evaluation emphasizes discount competitiveness, pricing compliance across product categories, and documented service-delivery capability — signaling that state procurement offices weight cost structure and vendor accountability alongside technical specifications.
