It is untested, but maybe You can write a little AGI-Script which
accesses some channel vars. Call that AGI as a DeadAGI. A DeadAGI will
be called, if a connection terminates (connect it with the
'h'-Extension, see the wiki). I don't know if the neccessary information
is still alive at this time, but maybe it will do what You want...

HTH,
