Fax pro sending faxes fail with Unknown error (Originate failed)

I can receive faxes all day. When I try to send a fax from the UCP I get the above error. The fax goes to retry right away. Am I supposed to have a special outbound route for this? I have the fax number in the Default Local Station Identifier

What are the logs telling you?

well I just found this:

I don’t see any errors in the logs. Maybe I’m not in the right area?
