The Flight Ops FAR 117 Bulletin says that by signing the FDR we are agreeing to the max flight extension possible unless the pilot not wanting to extend calls the dispatcher.

Does this mean I will have to call the dispatcher before every flight and tell him that even though I am signing the release, I do not agree to any FDP extensions that may arise later.

I don't think the intention of FAR 117 was for extensions to be automatic unless you call and tell them otherwise.
