hello Daniel

thanks for the response
we are using 4.4.1.
i will try to use async_route instead

i found making some tests that the error seems to happen when there is some delay in the connection with the FSW and we have a timeout, so it seems there is some relation with that timeout (with lua conn:bgapi it waits to receive an event) and having issue to do the t_suspend and t_continue.

best regards
david

I think async_sleep() is doing t_continue() internally, are you doing it
also in the config file or the error comes from inside the c code of
async_sleep()?

What version of kamailio are you using?

Also, it's better to use async_route() instead of async_sleep().

To get $ci in almost all logs (those that are printed when a sip message
is processed), you can set the log_prefix core parameter:
