What OpenVox does

OpenVox Communication Co., Ltd., founded in 2002 and headquartered in Shenzhen, China, designs and manufactures open-source-based VoIP and unified communications hardware and software. Its product portfolio spans the UScale X1981 unified gateway (supporting up to 20,000 users), the UCP Unified Communication Platform family in 1U/2U/4U chassis (UCP1600/UCP2120/UCP4131), the UC Series and Enterprise Series IP PBX systems (UC120P, UC200, UC300, UC501, UC1000, IX140, IX240, MC100), modular VoxStack and SWG wireless gateways supporting GSM/WCDMA/LTE with eSIM options, MAG series analog FXS/FXO gateways, DGW digital E1/T1/PRI gateways, a full telephony card line (analog, digital PRI, BRI, hybrid, transcoding), Simbank SIM management devices (64/128/320 channels), C Series IP phones and the Voxcon softphone, FA/FD failover appliances, and a Cloud Management Platform. Underlying technology is built on the open-source Asterisk telephony stack with SIP softswitch cores, modular hot-swappable single-board architectures, HD voice codecs, and certified interoperability with FreeSWITCH, 3CX, Elastix, Issabel, and VOS3000.

The company primarily serves small and medium-sized enterprises and branches of large enterprises that require cost-effective, on-premise VoIP and UC solutions, with secondary exposure to telecommunications service providers, government, and education verticals (via its Teaching-Smart Unit line). OpenVox monetizes predominantly through quote-based hardware sales — VoIP gateways, IP PBX, telephony cards, IP phones, and accessories — supplemented by SIM banks and failover devices. Go-to-market is channel-driven: a global network of authorized resellers, distributors, system integrators, and technology partners, complemented by direct sales through the Shenzhen factory, a Wuhan office, a USA branch in California established in 2013, and an India office. Pricing is not publicly disclosed; the partner program offers tiered discounts, sales leads, marketing resources, and an OEM program. The company claims presence in over 100 countries and sustains a 15,000+ member technical forum as a community and support asset. It is privately held with no disclosed institutional funding, M&A, or leadership changes in the source material.

Product overview

OpenVox offers a comprehensive VoIP communication portfolio spanning multiple product categories that work together as an integrated unified communications solution. The core platform consists of UScale (high-capacity gateway supporting 20,000 users) and the UCP (Unified Communication Platform) series in three sizes: UCP1600 (1U, up to 100 users), UCP2120 (2U, 100-1000 users), and UCP4131 (4U, 1000-10000 users). Supporting these platforms are the UC Series IPPBX systems (UC120P, UC200, UC300, UC501, UC1000) offering scalability from SOHO to enterprise, and Enterprise Series IP PBX (IX140, IX240, MC100) for larger deployments. VoIP connectivity is provided through VoxStack modular gateways supporting GSM/WCDMA/LTE (SWG series with eSIM options), analog FXS/FXO gateways (MAG2100), and digital E1/T1/PRI gateways (DGW-L304/L20X). SIM management is handled by Simbank products (64/128/320 channels). Hardware extensibility comes from telephony cards: Analog (A400-A2410), Digital PRI (D130-D1630), ISDN BRI (B100-B800), Hybrid (X204), and Transcoding (V100). IP endpoints include C Series phones (C200, C401, C220, C421) and Voxcon softphone. Cloud management, failover solutions, and teaching-smart units round out the portfolio.
