Company Spotlight: Obihai Technology Reinventing VoIP a Third Time

If your home or office phone system has any analog telephone adaptor (ATA) or one of several Cisco-branded IP telephones, you are using products originally engineered and developed by the team at Obihai Technology. In fact, while running Komodo Technology in the 1990s, Obihai’s founders, CEO Jan Fandrianto and VP of Engineering Sam Sin, helped launch the consumer VoIP industry when they invented the analog telephone adaptor. The company was bought by Cisco and the ATA-186 and ATA188 devices quickly became the de facto hardware standard for most of the first VoIP companies, including VoicePulse and Vonage.

Obihai Technology

Fandrianto and Sin left Cisco and formed Sipura Technology in 2002 and promptly revolutionized the industry again through a series of ATA and IP phones, each carrying the “SPA” moniker (SPA2000, SPA3102, etc.), that expanded the functionality of the original Komodo device at price points that rapidly advanced VoIP adoption internationally.

Again Cisco stepped in and bought Fandrianto’s and Sin’s Sipura in 2004, and the SPA adaptors quickly became the foundation on which the consumer VoIP space took off. The largest access independent VoIP service providers like Vonage, Telio (Norway) and iTALKBB have used Sipura-based designs for their subscriber equipment.

In 2010, Fandrianto and Sin left Cisco again and formed Obihai Technology. And again, the two are changing the world of embedded VoIP systems, this time with their powerful and flexible state-of-the-art OBi telephone devices. The OBi100 and OBi110 have been on the market for about a year now. Consumer reviews on, a primary reseller of Obihai’s devices, have been very favorable, with more than 85 percent of reviewers awarding the OBi110 the maximum 5 stars, significantly higher than its principal market rivals. In January, the OBi110 was recognized as Consumer VoIP Product of 2011 by Voxilla.

    So, you are saying that Cisco is going to eventually buy them as well? Not a bad idea… although I can’t think of any advancement that PAP2 has over SPA2000…

  2. Drew says:

    Ip PBX isnt just about Voip, there has to be more to it. Voip is now a commodity you have to have more. Predictive dialing and not a third party app, CRM,Recording, Historcial reporting…..more bang for your investment with maintenance and support built in

  3. the way i understand it is that Cisco was not interested in making any improvements with its PAP2 and other ATA’s and just kept Fandrianto and Sin languishing under the corporate umbrella

    and they finally had enough of doing nothing
