I tried with async module, but always got error ``` 2024-05-07T17:31:16.143660+03:00 siika /usr/bin/sip-proxy[2910444]: ERROR: async [async_mod.c:462]: ki_async_task_group_route(): invalid usage for faked message ``` and when I read async module README, all its functions deal with SIP request processing. `tcp:closed` event route does not have any SIP request.
So please restore the old working behavior.
