I have the exact same setup with my obi202.
The inability for the caller to not hear me seems to have happened to me after we had a power outage!!! However this problem is intermittent but seems to increasing in frequency. The next repeat phone call from the same person / source after hanging up will be totally ok.
Then, yesterday 10-18-16, I got this recorded message when trying to call out:
"Google voice error. If you changed your google account password, log into
obitalk.com and change it there as well"
So now I can"t call out.
When I log into Obitalk, I get this message:
"Your obi device is currently using an old or invalid @gmail password for connection to Google.
Please click <OK> to access the Google service settings then enter and submit your current Gmail password.
Your Obi device will restart with the correct password and connect to the Google Service"
I have not followed these instructions yet because I am researching these topics on this forum, on searching with google , and searching on obitalk.
Steve, please help!!!
