UNSPSC 43221530 Switch board signal device is a Commodity code that encompasses voice telecommunications infrastructure and systems procured by state and local education agencies. Recent solicitations under this code show school districts buying comprehensive telephone service solutions — both traditional circuit-switched and cloud-based Voice over IP systems — including handsets, PRI and POTS lines, SIP trunks, voicemail, fax support, and the associated installation, configuration, and ongoing support required to serve geographically dispersed campuses. The issuing bodies are primarily independent school districts and intermediate school districts, which use RFP processes to replace or upgrade existing phone infrastructure serving hundreds of facilities and thousands of users simultaneously.
