The much-admired new VoIP solution for small businesses.

How does paying less than $3 per month for VoIP service sound? If you haven’t heard of Obihai, you will soon (and not just through this blog). Obihai’s ATAs and VoIP adapters are quickly becoming popular as a means of providing affordable VoIP to businesses and homes.

Obihai is a fairly new Silicon Valley company founded by individuals well rehearsed in voice and video technology, manufacturing and marketing. The product of this collaboration is the Obihai brand of ATAs and VoIP adapters.

Obihai OBi100The OBi100 and OBi200 series ATAs are simple to install. Connect the OBi device to your Internet router or network switch, connect your phones and add a VoIP service (make sure VoIP service is compatible with the ATAs).

Through the OBiTALK service, OBi ATAs can provide completely free VoIP. Both endpoints must have the OBiTALK service and an OBi ATA, but after that, all you need is a phone and the Internet.

Otherwise, approved service providers cost OBi users on average of $120 (with OBi100 devices) or $130 (with OBi200 devices) per year. With approved services costing as low as $3 per month!

Setting up the OBi ATA through the OBiTALK web portal lets you integrate smartphones, computers and mobile devices with your compatible VoIP service. Choose an OBi model with an FXO port or failover capabilities to also integrate a PSTN. The Obihai OBi110 ATA, for example, includes both an FXS and FXO port.
