Yealink holds about 10 MA-L blocks under the newer registrant "YEALINK(XIAMEN) NETWORK TECHNOLOGY CO.,LTD." plus 1 legacy block (00:15:65) under the older "XIAMEN YEALINK NETWORK TECHNOLOGY CO.,LTD" — both map to the same vendor and should be normalized. The company is based in Huli District, Xiamen, Fujian, China. These OUIs appear on IP desk phones (the T-series), conference phones, video endpoints, DECT phones, and headsets. Yealink is one of the most common VoIP desk-phone brands in SMB and enterprise environments, alongside Polycom/Poly and Cisco. For triage, a Yealink OUI almost always identifies a SIP phone in the voice VLAN.
