Overcome an incoming call annoyance
Update – February 16, 2011: This section of the How-To is no longer valid as Obihai Technology has simplified configuration through both the configuration wizard and ObiTalk.com. Now, setting up Google Voice on the OBi using these methods (7A and 7C above) automatically enables the “X_SkipCallScreening” setting. You may now safely skip Step 8, though it remains online here for those interested.
Note: If you used the built-in device configuration tool as described in Step 7 (“The most complex”) you may skip this section and move on to Step 9.
When your Google Voice number is dialed and you pick up the call on the phone attached to the Google Voice-enabled OBi, you will be prompted to press 1 to accept the call or press 2 to send it to voice mail. The prompt is sent by Google Voice and, unfortunately, there is no way of bypassing it from the Google Voice settings. Fortunately, Obihai has a provided a work-around to the problem, accessible through the device configuration tool (expect to see the following as a setting on the OBiTalk page shortly).
First, you will need to know the internal IP address of your OBi. You can easily get this by picking up the phone attached to the device, dial “***” to get to the OBi “device configuration menu”, then select option “1″. Your IP address will be read back to you.
Enter the IP address on your browser and you will be prompted for a user name and password. For the user name, enter “admin”. The password is whatever you set in the “Webpage Admin Password” field for the device in OBiTalk (Step 7 above).
Click on the plus sign next to “Voice Services” in the left column to expand the menu, then select either “SP1″ or “SP2″, which ever service provider you chose to put Google Voice on in OBiTalk (in Step 8). Scroll to the bottom of the screen.
The Obi SP1/SP2 configuration. X_SkipCallScreening is at bottom
The bottom setting on this page is called “X_SkipCallScreening”. Click and uncheck the blue box under the “Default” heading for this setting, then click and check the box under the “Value” tab. The settings should look like the image above.
Click the “Submit” button, at the bottom, click “OK” to submit the changes, then click the “Reboot” button at the top right of the screen. in a few seconds your OBi will reboot and the annoying call screening prompt will be effectively removed.
