Obihai OBi302 Overview

The OBi302 by Obihai is a 2-port ATA which will allow you to use your analog devices with any SIP trunking provider. Simply plug the Analog Telephone Adapter into your broadband router and then plug your analog devices into the ATA. Calls from your OBi302 to any other device on any OBi device anywhere in the world are always free! The OBi302 features 2 FXS connections so you can connect 2 analog phones, an analog phone and a fax machine, or 2 fax machines to the Internet to enjoy VoIP calling. The OBi302 also has 2 RJ45 ports, so you can connect to your broadband router and to another IP device such as a PC. The 2 port RJ45 router has integrated QoS to ensure your voice traffic is prioritized above other types of traffic. It will support up to 4 VoIP services or SIP accounts. The OBi302 also features a USB port which allows you to plug in USB devices such as the OBiWiFi wireless adapter which allows it to work anywhere within range of your wireless router without a cable connection.

The OBi302 is easy to use and setup. When used with a SIP service provider, you will enjoy value-added features such as message waiting indication (MWI), speed dial, three-way conferencing, caller ID name and number, call forward, call waiting, Do-Not-Disturb, Call return, call recording, call history, and automatic attendant. Using an OBi302 with an analog phone as a SOHO telephone system gives you big company features at a consumer price.

The Obihai OBi302 is the lowest cost, fastest deployment ready ATA with zero touch customization (ZT). The OBi302 can be deployed directly to customers, redirecting automatically to your provisioning server or you can use the OBiTALK ITSP portal for target profiles. The Obihai ZT customization is available to service providers with a very low minimum order quantity. SPs can support customers using the OBITALK ITSP management portal which allows the SP to access each device individually to remotely troubleshoot and unobtrusively configure specific parameters on a customer's device. The OBi302 is a best-in-class ATA for service providers and their customers. The phone port collaboration makes the OBI302 a mini-phone system when needed for small businesses. The USB port, which supports the OBiWiFi or OBiBT dongle among many other applications, allows customers to use their OBi302 anywhere within range of a WiFi router or Bluetooth device. Cloud-based management of devices via OBiTALK portal gives SP's total visibility and control over deployed VoIP adapters.

Questions on Obihai OBi302 - 2 FXS ATA with Router and QoS

From Herbert Childs at 4/8/2013 8:27 AM

Q: I have been looking at options to close my landline for sometime and the OBiHAI adapters look promising. I see in a couple of places that this unit does not support Google Voice as some of the other OBiHAI units. Since I already utilize Google Voice, it would be desireable that it work with it. Does this unit work with Google Voice or is there another comparable OBiHai unit with this capability?


A: Hello!

The OBI302 does NOT work with Google Voice. This is more carrier-grade meant for Service Provider VoIP deployments. If you are looking to just use your home analog phone with Google Voice, the OBI100, OBi110, or OBi202 will work for you.

-The OBi100 is the most basic and will allow you to connect one phone to Google Voice.
-The OBI110 will allow you to connect one phone to Google Voice and also allow you to use your landline for local calls, including 911. Remember, Google Voice does not support 911 services.
-The OBi202 has a USB port which will allow you to use an OBIWiFI or OBIBT dongle. This is handy if you want to use your Obihai and your analog telephony nowhere near your router. As long as you have a WiFi router, you can put your phone anywhere in your house within range of the router.

I got rid of my landline and use Google Voice with an OBI110 solely in my home and it works great! I did the same for my Dad.

I hope this helps you make your decision!

Q: Will this unit work with Asterisk? We're using Grandstream ATAs in two locations, with complete success. In the 3rd location I can't keep the ATA from crashing - and it does not appear to be a network issue (the IP security camera at that location, plugged into the same switch does not crash)
