Thanks for the information. Have one more  related question.

What If I call somewhere, opensips calls wait_for_event() and before the event happens or async timeout (will create a bug report) fired I CANCEL the call. Since async() keeps some context in transaction structure and this transaction is already canceled should I expect that async() task is also canceled and will never call a callback route? Or should I always check  t_was_cancelled() in the beginning of a callback route?


Hi Vitalii,

For the wait_for_event(), the timeout seems to have no effect, the waiting being for ever :-| . The transaction has no timeout as you didn;t sent out any branch yet (the transaction timeout is for waiting on replies).

Could you please open bug report on the opensips tracker on github ?

Hi,

event_routing module provides the great async function wait_for_event().  If script subscribes for a event and received it it calls some "resume_route". What I can't understand is what happens with a transaction if wait_for_event() never catches an event and reaches its timeout. Is the any way to continue script execution from the place where "wait_for_event() was called or to execute some "timeout_route" to handle transaction properly?
