Okay, I think you're proving the OP point on the hangup and/or "h"
extension. The above _does_ work, however that certainly is a very
convoluted way to cause a simple hangup.

I think the real issue is that hangup and/or the "h" exten have been
around for a long time and many changes have occurred in how the
dialplan is interpreted since then. But, no one has really gone back
to analyze how the hangup should truly function in the current
dialplan environment.
