LVSWITCHES INC. (trading as "LVswitches Inc.") holds two MA-L (OUI-24) blocks in the IEEE registry — B8:12:DA and 84:3B:10 — both registered to the same address in the New Light Source base, Luocun town, Nanhai district, Foshan, Guangdong, China. The company is a Chinese OEM/ODM manufacturer of VoIP and unified-communications hardware: IP PBX systems, SIP desk/wireless/video phones, analog and media gateways (FXS/FXO/PRI), IMS soft-switch platforms, IP intercom terminals, 5G wireless routers, and accompanying call-center and billing software. Its MAC-OUI footprint covers the Ethernet interfaces embedded in those telephony appliances, which sit at the PSTN/SIP edge of enterprise voice networks. The vendor self-reports a 2005 founding and broad distribution (claims of 100+ countries and tens of thousands of clients are vendor-stated and unverified). Because LVswitches gear is SIP edge equipment, the relevant security posture is category-level rather than product-specific: no LVswitches-attributed CVEs or advisories were found, but IP PBX and SIP gateway devices from any vendor are exposed to toll fraud, SIP brute-force, and DoS if default credentials, open SIP ports, or firewall rules are left unhardened. IEEE publishes no assignment date for OUI blocks, so allocated_date is Unknown — not fabricated.

- Security note
- No LVswitches-specific CVEs, advisories, or documented exploits found as of June 2026. Category-level risk: SIP/IP-PBX edge equipment is exposed to toll fraud, SIP brute-force, DoS, and unauthorized access if defaults/firewalling are not hardened. No threat intel attributes attacks to LVswitches hardware. [Confirmed — category guidance] — https://www.ncsc.gov.uk/guidance/private-branch-exchange-best-practice
- Analyst note
- An LVswitches OUI (B8:12:DA / 84:3B:10) on a globally-administered address identifies genuine LVswitches telephony hardware; treat such devices as SIP/PSTN-edge appliances warranting credential hardening and SIP-port firewalling.
