Hello,
I have a question about the rtpengine module and how to use it via KEMI/python.
Will processing of the native script stop when rtpengine_manage returns with an error?
Or will it continue and will the SDP be forwarded unchanged?
#!ifdef WITH_RTPENGINE
if(nat_uac_test("8")) {
rtpengine_manage("SIP-source-address replace-origin
replace-session-connection");
} else {
rtpengine_manage("replace-origin replace-session-connection");
}
#!else
Regards,
Wolter

The second one. However, mind the timeout modparams for the `rtpengine` control module.
With the defaults, outreach efforts to an unreachable RTPEngine (assuming that's the
error) will rapidly block your SIP worker processes.

Not sure how the handle the failure in case rtpengine_manage fails handeling the reply or
ACK with SDP.

Hi,
rtpengine_manage() will return -1 if any errors happen. You need to
check the return code in kamailio cfg file and explicitly end SIP
routing logic if you want so. Otherwise, SIP routing logic will continue.
Thanks,
Stefan

I suppose this is a matter ripe for controversy. The answer might depend on whether you
have a fallback scheme absent RTPEngine, and whether you want calls to overtly fail as a
matter of optics and/or politics. :-)
