But what I thought you were originally saying was that the 'h' extension
would NOT be executed if the callee hung up, and that it was necessary
instead to use the 'g' option to continue in the dial plan in order to do
whatever would otherwise have been done in the 'h' extension.

My experiment was to demonstrate that this is not the case, and that the 'h'
extension is available to the calling channel whichever end initiates the
hangup.
