Hi Mark,
Mine still is not working, and I don't expect that it will get fixed. In response to a query that I sent to OBi, they asked me to disconnect the OBi (power it off), then log into the GMail account I used for the GV number and try to call it from there. I got the same busy tone, so the conclusion is that it is a Google problem. I have had no response on the GV forum. If you want to try calling yourself from the computer, there are "talk" buttons on both the Google Voice page and the GMail page, and I vaguely recollect that you can get different results depending on which one you use (the GMail page may even require an applet download)--so try both to rule all out options. If you get a busy signal dialing from the computer, then it is probably a GV issue, and I have not yet found a solution.
Here is my workaround in the meantime: open a new GMail account and grab a second GV number. Provision this second number on the Obi202's SP2. Then, on your phone VM access number, program in **2, followed by your original number (the one you ported), followed by a couple of pauses, followed by *, followed by your GV voicemail password, if any. Basically, you are accessing your voice mail from a remote number--the **2 at the beginning tells the OBi to dial out with the second line (SP2)--on my Panasonic phone the command is **2#######PP*### (where the first seven numbers are my ported numbers and the last four are my GV VM passcode for that number, two pauses seems to give enough time, but you can play with that). If you have a two-line phone, you could just provision SP2 on line 2, and then you wouldn't need the **2 command. This solution is okay, until the day they start charging for GV, then it would royally suck--paying for a second line just to access a feature of the line you really want!
