[SR-Users] Re: Information about Kamailio operating as an SBC
As there is no such consistent thing as SBC you may start at first with the definition of the components you whish to have according "sbc" terminology. The good start is from here: https://datatracker.ietf.org/doc/html/rfc5853 Then, once you understand exactly what you would like to have on board the best good entry point will be https://www.kamailio.org/wiki/ Going through the config examples and kamailio docs you will be able to find the best way to achieve your needs.

[SR-Users] Re: Information about Kamailio operating as an SBC
Hello, I have Kamailio version 5.6.4. I have installed rtpengine version 11.5.0.0. I have the RTP through the kamailio. The machine has just one NIC and all is working fine. I would like to have two NICs: One NIC for the private network and other NIC to the public network. I am looking information about Kamailio operating as an SBC. Where I can find more detailed technical information ?

[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.sanity_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.

I used to have this problem, but I don't have it right now. I've never
fixed the problem, but I'm on 5.6.1 now and it doesn't happen.
What version have you got?
