Hello, don't do explicit t_suspend() if you are calling the async_task_route() because it is done internally.
I presented a way for async push notifications during the Kamailio World Conference 2014, see: - http://www.kamailio.org/events/2014-KamailioWorld/day2/26-Daniel-Constantin.Mierla-Kamailio.cfg-Async.pdf A video should be also on youtube.
