You nailed it. That is what I did and it appears to have worked for me. Your email was just a little late, Still appreciated as was everyone else’s responses.

 I created two IAX trunks for now. There is one for each of the two BBB that I have available right now. I have tested one unit so far and I may go back and visit this more tomorrow. I'm thinking one trunk to the hub and then connect the other nodes from that point. Instead of connecting each mode to the two PBX's here at the house.
