It turns out that the OBI is connected to a business phone system in Brazil. When the power went out, and all had to be reset, the business system, went back to a default setting, which was pre-converting the Caller ID information, to the U.S. system, before it reached the OBI!
I returned the parameter in the OBI back to the US type, and all is working well.
I have a second installation, at a residence. This should be using the Brazil/Swedish system. I will leave a post when I get this working Larry
