After firmware update my OBI100 wouldn't work anymore. I couldn't reinstall google voice connection. Well after 2 days it is working now. First - google voice must have a gmail address not some other email. Next google mail must have chat - in gmail click the phone icon to make a call, make call, then click more option and add chat . Then remove device on Obi account and reinstall. Without gmail address could not connect sp1. Without chat I could dial out - always got a busy. I hope this helps.
