  CDR's are being written immediately on caller hangup.  The dialplan is not
  able to modify it in the h exten.  The h exten in the initial context is
  not run before closing CDR's when the bridge is unlinked if a macro is
  active and does not have an h exten.
  
  * Make ast_bridge_call() check for an h exten in the current context and
  if a macro is active then the initial context.  The first h exten found is
  then run before closing the CDR.
