Hi
AlanM,
I understand why the controller needs the dump point to effect the handover and/or termination of service.
Controllers tend to use obvious geographical points
This one wasn't obvious and we had a mis-understanding of the placename via R/T. I think geographical boundaries like coasts, piers, estuaries etc. are great for this sort of thing: towns are not always so distinctive but probably second best.
Anyway, as above, I concede it was not a big deal
