[Fixed] OBi110 is not working with Google Voice

Just a few days ago, my OBi110 device does not work with my Google Voice. I can not dial out, and no incoming call, until today, I fixed it.

Sometimes it said some configuration error. I sign in my OBiTalk account at https://www.obitalk.com/obinet/

Normally, the device OBi110 can do the firmware update through the OBiTalk account dashboard. but it did not work this time.

When I sign in my account, then go to the device configuration page. I can setup Google Voice account by clicking the gear icon beside the account. But, now it is shown a warning or error without setup.

obi110-not-updateThe error displayed is Authentication error.

Now, let me show you haw to fix this error. the most important part is to upgrade the firmware of the device.

The latest firmware is 1-3-0-2886, the current one on my OBi110 is 1.3.0 – 2872

The following is the official guide of upgrading.


  • Pick up the phone attached to your OBi and dial ***1 and write down the IP address that it reads to you.
  • Open a web browser to that address.
  • Log into your OBi device.  The default username and password are both admin
  • Click System Management–>Device Update–>Firmware Update–>Select file to update firmware.
  • Browse to the file you downloaded and select it.
  • Click the “Update” button.
  • Watch the OBi’s LEDs and wait for the device to successfully reboot, before continuing.
  • You may need to re-authorize your device to use your Google account after this procedure.  To do that, first, be sure that you are logged into the correct Google/Gmail account that holds your Google Voice number.  Then, open another web browser tab, and log into to the OBiTALK dashboard, click on your device, then click on the Service Provider (SP1 or SP2) that is using Google Voice.  Click “Accept” at the prompt.  On the window that will open, click the link to “Replace Google account credentials” and follow the instructions.
  1.  I download the firmware directly from this link http://fw.obihai.com/OBi110-1-3-0-2886.fw  I am also saving a copy here for your downloading.OBi110-1-3-0-2886 1.7MB
  2.  I find the IP address from my Router dashboard. Because my device and desktop are not in the same room.

Here are some screen shoot for records.


Look at the software version. 1.3.0 (build 2872) It is the old one. And the status of SP1, which is my Google Voice account, said the failed connection.


After updating the firmware, I signed in OBiTalk account and click SP1 config gear icon, Look at the link I pointed with a yellow arrow. Click it and confirm the authorization of Google Account.

google-voice-connectedWhen I finished re-config the Google Voice account above, the device information said my Google Voice Account is connected.

new-firmwareNow the last step, to double check the status, firmware on device dashboard. The software is 1.3.0 (Build 2886). The SP1 Service Status is connected.
