OK, that's the "stutter tone". It can indicate either a voicemail message waiting, or that your phone number has been unconditionally forwarded to some other phone number.
We'll blame it on your two-year-old.
There are many reasons why inbound calls don't ring on the OBi:
- Your phone's ringer is turned off or broken.
- You don't have a check mark to the left of "Google Chat" on this page: https://www.google.com/voice#phones
- You set up your OBi using the wrong Google account's credentials (using an account that doesn't actually have an inbound Google Voice number.
- You enabled Google Voice's "Do not disturb" feature.
- You set up a ring schedule on Google Voice, such that your number is intentionally not ringing.
- and, more...
Years ago, Google Voice supported sending the voicemail waiting signal, however, that function was discontinued. Google Voice doesn't support unconditional forwarding via telephone commands, so that's not it.
Perhaps you have old firmware on your device, and/or you have set it up incorrectly. The definitive way to eliminate all possibilities is to upgrade the firmware on your OBi, factory reset it, and set it up again with Google Voice.

http://www.obitalk.com/forum/index.php?topic=11384.0At the end of that post is a link to my complete instructions for setting up Google Voice from scratch. I suggest factory resetting your OBi and following those steps.
To do that, first log onto the OBiTALK web portal. Click the OBi device. Click "Delete Device". Wait for several minutes. Then, pick up the phone and press ***8 then 1 to confirm restoring to factory defaults. Wait until the LEDs stop blinking, except for the internet LED flickering.
Click the Add device link on OBiTALK, and follow the **5 procedure to add it back. Then set up Google Voice again, following my instructions carefully.
