From what you said I can pretty much assume that you do not have to worry about restricting TIE trunks from talking to Loop Start rtunks etc. so just make sure that all colums and rows from 1 to 6 have stars (*) in them. Also make sure that you have "Call forwarding external enabled" in the trunk Class of service and "Incoming to outgoing call forward" enabled in form 4. Also I would suggest that in the console class of service you enable all the trunk to trunk connect options - again so you don't have to worry about what kind of trunks you have. I have this kind of thing working in switches all over the place.
