hey

i have release 1.2.1 code base,
the state handler is called in Windows, but not in Ubuntu 12.04

here is the code:

static switch_state_handler_table_t channel_event_handlers = {
/*.on_init */ NULL,
/*.on_routing */ NULL,
/*.on_execute */ NULL,
/*.on_hangup */ channel_on_hangup,
/*.on_exchange_media */ NULL,
/*.on_soft_execute */ NULL,
/*.on_consume_media */ NULL,
/*.on_hibernate */ NULL,
/*.on_reset */ NULL,
/*.on_park */ NULL,
/*.on_reporting */ NULL,
/*.on_destroy */ NULL
};
......
if (switch_channel_add_state_handler(hook_channel, &channel_event_handlers) < 0)
      {
   switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(session), SWITCH_LOG_ERROR, "state handler added failed\n");
      }
.......


Anyone knows why?
