E: Unable to locate package libxmlrpc-c3-dev
Trying to install these pkgs:
libxmlrpc-core-c3 libxmlrpc-core-c3-dev
No such a package in Debian!(( libxmlrpc-c3-dev , trying without it…
Trying without it and get an error:
The following packages have unmet dependencies:
libcurl4-gnutls-dev : Conflicts: libcurl4-openssl-dev but 7.52.1-5+deb9u6 is to be installed
libcurl4-openssl-dev : Conflicts: libcurl4-gnutls-dev but 7.52.1-5+deb9u6 is to be installed
The conflict was because of need either gnutls or openssl. I installed gnutls:
apt install debhelper iptables-dev libavcodec-dev libavfilter-dev libavformat-dev libavutil-dev libbcg729-dev libcurl4-gnutls-dev libevent-dev libglib2.0-dev libhiredis-dev libjson-glib-dev libpcap0.8-dev libpcap-dev libpcre3-dev libswresample-dev libxmlrpc-core-c3-dev markdown
Now dpkg-checkbuilddeps shows no errors! :)
Trying to create packages:
dpkg-buildpackage
Success!!!

Trying to install ‘ dpkg -i ngcp-rtpengine-kernel-dkms_6.3.1.1+0~mr6.3.1.1_all.deb’
Get and error about ‘dkms’ package abscence.
Trying to install ‘dkms’ – errors about some packages abscence. Offers to do ‘apt –fix-broken install’. I agree, and it installs many additional packages.
I try to install these created packages again:
ngcp-rtpengine-kernel-dkms_6.3.1.1+0~mr6.3.1.1_all.deb

ngcp-rtpengine-utils_6.3.1.1+0~mr6.3.1.1_all.deb
At this moment I check installed packages with ‘dpkg -l | grep ngcp’ and see that they are alll already installed, marked with ‘ii’, but I go on:
ngcp-rtpengine-iptables-dbgsym_6.3.1.1+0~mr6.3.1.1_amd64.deb

Seems strange that this package hasn’t been installed as a dependency:
apt install ffmpeg
At this moment, rtpengine supports these codecs:

Rtpengine minimal start command:
rtpengine -i enp0s3/10.145.213.88 -l 10.145.213.88:9876
For these WARNS in syslog:
Jun 20 17:35:13 debian-opensips rtpengine[4029]: WARNING: Failed to properly parse UDP command line '4296_1 d7:command4:pinge' from 127.0.0.1:60637, using fallback RE
found this:
https://github.com/sipwise/rtpengine/issues/266
Advice – to start with ‘–listen-ng’ option:
rtpengine -i lo/127.0.0.1 --listen-udp=127.0.0.1:12221 --listen-ng=127.0.0.1:12222
or with CLI support:
rtpengine -i enp0s3/10.145.213.88 --listen-ng=10.145.213.88:12222 --listen-cli=10.145.213.88:12555
to use it:
rtpengine-ctl -ip 10.145.213.88 -port 12555 list totals
And modify OpenSIPS config (add new port with NG):
modparam("rtpengine", "rtpengine_sock", "udp:localhost:12222")
Works!!!
# rtpengine, may depend on tm // (optional) if you want to have rtpengine_manage() fully functional
# rtpengine -i enp0s3/10.145.213.88 --listen-ng=10.145.213.88:12222
loadmodule "rtpengine.so"
modparam("rtpengine", "rtpengine_sock", "udp:10.145.213.88:12222")
Great! OpenSIPS starts without any warnings.
OpenSIPS config:
What flags to use (by Kirill Galinurov):
$var(rtpengine_flags) = "RTP/AVP replace-session-connection replace-origin ICE=remove"
rtpengine_offer("$var(rtpengine_flags)");
My rtpengine re-writes SDP with 127.0.0.1 IP address – because I started it listening on 127.0.0.1.
But we need to start it on a non-localhost IP address.
By Kirill Galinurov:
RTP_IP[0]=external/185.128.105.15 # (m) Local IPv4/6 address for RTP. The format of the value is [NAME/]IP[!IP].
RTP_IP[1]=internal/172.20.99.247
“loopback is also possible”:
lo: mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet 185.128.105.15/32 brd 185.128.105.15 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
To start re-writing of IP addresses in SDP, don’t follow rtpengine module docs,
but just create global onreply_route, and use there rtpengine_answer() function without flags.
After that, you’ll have IP addresses in SDP rewritten.
But still no transcoding at this stage(
if (is_method("INVITE")) {
lookup("location");
if (has_body("application/sdp")) {
#if (rtpengine_offer("RTP/AVP replace-origin replace-session-connection ICE=remove codec-mask-PCMA codec-strip-PCMU transcode-PCMU"))
if (rtpengine_offer("RTP/AVP replace-origin replace-session-connection ICE=remove always-transcode"))
#if (rtpengine_offer("RTP/AVP replace-origin replace-session-connection ICE=remove"))
t_on_reply("1");
} else {
t_on_reply("2");
}
}
if (is_method("ACK") && has_body("application/sdp"))
rtpengine_answer();
route(relay);
onreply_route
{
if (has_body("application/sdp"))
rtpengine_answer();
}
