Sipura Technology, Inc. was a VoIP enterprise headquartered in San Jose, California, established in 2003 alongside VideoCore and Komodo Technology. The company specialized in creating VoIP telephone adapters, including models such as the SPA2100, SPA3000, and SPA9000, as well as IP telephones like the SPA941.

On April 26, 2005, Cisco Systems acquired Sipura and incorporated it into its Linksys business unit. Following the acquisition, the SPA product line was sold under the Linksys brand until the eventual sale of Linksys itself. Cisco maintained ownership of the underlying technology and continued to market the SPA series under the "Cisco Small Business" label for several years thereafter. In 2016, Cisco introduced the 7800 and 8800 series IP phones featuring "3PCC" models that operated on updated firmware originally created by Sipura.
