Above build 2824 your OBi100 GV must be setup on OBiTalk because of a new GV authentication method.
An OBi100 with build 2824 uses the old method and I think must be setup locally.
You might be able to configure it using OBi Expert and not the GV wizard, I have not tried this.
I have an OBi110 at build 2824 that I configure locally.
I recommend configuring it locally.
Make the following changes locally:
Service Providers -> ITSP Profile A -> General -> SignalingProtocol: Google Voice
Voice Services -> SP1 Service -> AuthUserName:
GV_ID@gmail.comVoice Services -> SP1 Service -> Password: GV_Password
After you make the changes on a page click SUBMIT at the bottom of the page.
After you make all the changes click REBOOT at the top of the page.
After the reboot look at the System Status page.
The status of SP1 should be CONNECTED.
