To try to fix the issue I had rebooted the Obi, at 19,30 , on 5/3/2007, but, no luck....
Made a call through Google Voice and and it worked just fine.... Consequently, there is an issue from Obihai.
Submitted a ticket for the issue and looking to receive a resolution asap.... as, I need my line back.
This is the response from OBI support team @ 19,33:
"There is a temporary service issue with Google Voice at this time, affecting certain Google Voice users with the OBi.
The issue is being worked on and please wait for Google to resolve this issue. In the meantime, you don't have to do anything to your obitalk configuration.
Thank you, - OBi Support"
Made a call around 21,45 CT and Obi it was working just fine...
