You can handle the 'h' extension in the dial plan, which will supply the 
${CHANNEL} that was hung up, and possibly some additional dial plan 
variables as well:

Using these, you can piece together who hung up on whom, etc.

#2 is handled by fallthrough in the dial plan that causes the 
instructions to continue executing to the next priority for that 
extension, whereas if the call completes (Dial() is successfully 
connected), this does not happen.
