Hi,

I think that i need more in depth understanding how this works - i
need to use rtpengine_ofer - before TLS w/ sRTP hits my kamailio
script ? and then, rtpengine_manage towards the no-SRTP endpoint, and
then - finally rtpengine_answer - ? So - 6 times - rtpengine_X ? (one
for incoming leg, 2nd for - outgoing)
Thanks for your input on this.

Mayby any working example - this is preety common use of rtpenine +
kamalio i think, but - well - every available article is - old like 7
years ago or - does not cover this scenario.
if (proto==TLS) {
rtpengine_manage("RTP/AVP ICE=remove replace-session-connection
replace-origin pad-crypto ptime=20 codec-transcode-PCMA record-call=on allow-transcoding
direction=external direction=internal record-call=on");
} else if ($ru =~ "transport=tls") {
rtpengine_manage("DTLS=on SRTP AVPF ICE=remove
replace-session-connection replace-origin pad-crypto ptime=20 codec-transcode-PCMA
record-call=on allow-transcoding direction=internal direction=external record-call=on
media-address=1.2.3.24");
}
Double check that one of these is actually triggered for each
offer/answer (invite/ok).
(Your usage of `media-address` is probably not what
you want - usually
it's the "advertised address" syntax of the interface config that people
want)
Looking into that!

This looks like no "answer" was seen, which is what makes me think your
script doesn't actually trigger the function for the answer.
