Hi: that suggests you have made a mistake somewhere in the configuration steps. Possibilities include being signed into the wrong Google account (an account that doesn't have Google Voice set up yet), or the authentication to your Google account failed.
Rather than guess, the best approach would be to delete your OBi off of your OBiTALK dashboard, then factory reset the OBi (press ***8 and then press 1 on the attached telephone) and start over from scratch, first adding the OBi back to your OBiTALK dashboard.
Read and follow my detailed instructions here, to make sure you have not missed anything:

First: log out of all things Googley on all your web browsers. Clear the browser's cache, cookies and history, close and then reopen the browser. Go here and log in:
https://www.google.com/voice#phonesLook at the left side of the page, and confirm that it says the exact two words, "Your Number", and not any other phrase. Leave that web page open, press Ctrl-T to open a new browser tab, and log into your OBiTALK account. This will ensure that the correct Google account is being used.
