What Ozeki Informatics does
Ozeki Informatics (operating as Ozeki Ltd) is a privately held Hungarian software vendor founded in 2000 and headquartered in Debrecen, Hungary. The company develops and distributes Ozeki Phone System XE, a Windows-based software PBX that transforms a conventional computer into a multi-channel communication server. The product is built on the proprietary Ozeki VoIP SIP SDK and runs on the .NET Framework 4.0, supporting SIP 2.0 for VoIP, SMPP and GSM 07.07 for SMS, and Flash/HTML5 for webphone technology. It supports up to 1,000 simultaneous calls per node, 4,000 SIP clients per node, and 500 SMS messages per second per node, with text-to-speech in 26 languages and 3D video call capability.
The product consolidates voice, video, SMS, and browser-based real-time communication into a single platform, and integrates with ISDN (via CAPI 2.0), analog, GSM, and VoIP/SIP telephone networks, as well as ERP/CRM and SQL databases through .NET, HTTP, SQL, JavaScript, and OzML APIs. Code examples are published in nine programming languages, targeting developer and IT administrator buyers.
Ozeki operates a sales-led, product-led, and channel-partner GTM mix. Revenue is generated primarily through one-time perpetual software licenses priced by simultaneous call capacity, with optional annual maintenance and support (silver/gold packages). The company extends reach through a multi-tier partner program (software resellers, VoIP service providers, hardware vendors) and a self-serve download and purchase model on ozekiphone.com, with a 20-day free trial. Customers are segmented horizontally across SMB, mid-market, enterprise, IT integrators, and telecom service providers, served globally across 24+ countries.

Ozeki Informatics competitors and assessment
Company assessmentDirect peers
- Grandstream Networks: Grandstream provides IP PBXs (UCM series) and SIP endpoints with a channel-driven sales model similar to Ozeki. It targets the same SMB/integrator segment with software-based PBX and broad hardware compatibility.
- 3CX: 3CX is a software-based PBX (on-premise and cloud) for Windows/Linux with similar SIP-based telephony, video, and webphone features. It competes most directly with Ozeki Phone System XE among SMBs and integrators looking for software-only PBX solutions.
- Yeastar: Yeastar provides on-premise and cloud PBX software (P-Series, S-Series) targeting SMBs and channel partners, with comparable features (IVR, call queues, multi-site, integrations). It competes in the same SMB-to-mid-market PBX software category as Ozeki.
- Sangoma (Asterisk/FreePBX): Sangoma owns Asterisk and FreePBX, the dominant open-source telephony platforms, and sells commercial PBX software and appliances. It directly competes with Ozeki in the open-source/commercial PBX software segment with comparable SIP, IVR, and multi-channel capabilities.
Broad incumbents
- Avaya: Avaya is a large incumbent provider of enterprise unified communications and contact center solutions (IP Office, Aura). It overlaps with Ozeki in mid-market PBX deployments but offers a broader portfolio including cloud, hardware, and services.
- RingCentral: RingCentral is a leading cloud UCaaS/CCaaS provider, competing for the same communications budgets as Ozeki but via subscription cloud delivery. It is a broad incumbent shaping buyer expectations away from on-premise PBX.
- Mitel: Mitel provides on-premise and cloud UC solutions (MiVoice, MiCloud) for SMB and enterprise, with comparable PBX functionality and channel partnerships. It is a broader incumbent overlapping with Ozeki's on-premise PBX use cases.
- Cisco (Webex Calling / Unified Communications Manager): Cisco offers enterprise UC via Cisco UCM on-premise and Webex Calling cloud, overlapping with Ozeki at the enterprise telephony layer. It is a broad incumbent with a much larger portfolio of networking, collaboration, and contact center products.
Others
- Twilio: Twilio provides programmable communications APIs (Voice, SMS, SIP) comparable to Ozeki's SIP SDK and developer-oriented APIs. It is an adjacent enabling platform rather than a direct PBX competitor, but it serves many of the same developer/integrator use cases.
Emerging players
- FreeSWITCH / SignalWire: FreeSWITCH is an open-source telephony platform (SignalWire is the commercial entity), directly comparable to Ozeki's SIP SDK and programmable PBX. It competes for developers and integrators building custom telephony applications.
