Hi,
Thanks for the reply,
When I was testing, I found the below log.
Log ==== *DEBUG: sl [sl_funcs.c:462]: sl_filter_ACK(): SL local ACK
found -> dropping it!*

Hello,
the sanity module can be used for request and reply checks, as e.g.
visible in the default configuration.
It might be a bit too short documented in the module readme.
Cheers,
Henning Westerholt

Subject: [SR-Users] Re: Inquiry Regarding Kamailio Behavior and Drop
Requests
I expect that it's not related, because the documentation is clear that
the
function relates to requests, not responses.
https://kamailio.org/docs/modules/5.5.x/modules/sanity.html#sanity.f.sanit
y_check
- 4.1. sanity_check([msg_checks [, uri_checks]])
- This function makes a row of sanity checks over the given SIP
request...
It seems simple: check the logs from the xlog command and see what you
find.
If it's not clear enough, add the Call-ID to
the log message, and then
also
capture (tshark/tcpdump) traffic for subsequent
analysis.
