From the hangup handler specification:

Hangup handlers are an alternative to the h extension. They can be used 
in addition to the h extension. The idea is to attach a Gosub routine to 
a channel that will execute when the call hangs up. Whereas which h 
extension gets executed depends on the location of dialplan execution 
when the call hangs up, hangup handlers are attached to the call 
channel. You can attach multiple handlers that will execute in the order 
of most recently added first.

Cool. So in my case where every context has:

         exten = h,1,                    goto(finish-call,h,1)

a hangup handler established at the start of the call makes perfect sense 
and prevents stupid errors like forgetting to list the template in the 
context declaration.
