Hi,
I finally resolved my issue, although without ever finding the cause. I am
using bare-metal servers from Vultr and I was having the issue with the
Debian 11 image that they provide when provisioning the server. An
external consultant and myself invested several hours trying to find what
could be causing this issue and we were unsuccessful. We tried everything
(or so we thought), including sysctl and various network settings, to
no avail. As a last resort, I then proceeded to wipe the server and
reinstall Debian 11 using the standard Debian network installer in
replacement of the image provided by Vultr. The problem magically went
away after doing so but I would really like to know the cause.
Cheers,
Michel Pelletier

Hi Everyone,
I’m having the same issue but believe it’s related to my network topology.
I have multiple carrier-facing NIC’s and an internal NIC on each media
proxy.
Is this configuration supported?
I have the named ‘public / providerA / providerB’ rtpengine interfaces
setup and working correctly – media flows as expected when running
rtpengine *without* the kernel module.
When kernel module is in use I get a few seconds of 2-way audio initially
before it drops out in one direction usually.
[root(a)per01-mtp01.dev.xyz blah]# cat /proc/rtpengine/0/list
local inet4 203.x.x.x:40000
stats: 350880 bytes, 2040
packets, 0 errors
RTP payload type 0: 0
bytes, 0 packets
RTP payload type 8: 350880 bytes,
2040 packets
SSRC in: 65aa31af
output #0
src inet4 10.y.y.y:40000
dst inet4 203.x.x.x:39302
SSRC out:
I was also looking to find some config to make this working using
firewalld rules, fishing through the Sipwise repos I stumbled across some
firewalld rules as part of their automated builds but didn’t have any luck
with them
If somebody had some rules I could try would be much appreciated!
Cheers,
Tim

Hello,
Thank you for your reply. I checked the versions and they look good.
xt_RTPENGINE is 11.1.1.3 and the daemon is 11.1.1.3-1~bpo11+1. Looking at
/proc/rtpengine/0/list I see the packet and byte counters incrementing
normally with 0 errors. In wireshark, capturing on any, I see the stream
coming in on the private network interface but nothing going out through
the public network interface. Everything is good until 5 seconds into the
call when the kernelization happens.

I am proxying all RTP through RTPEngine.
Everything works fine until
about 5 seconds into the call, when rtpengine enters kernelization,
after which all RTP forwarding ceases. I've checked the required
iptables entries, and all looks good.
Inspect /proc/rtpengine/0/list while a call is running, in particular
paying attention to the packet and byte counters.
Also double check that the version of the rtpengine daemon matches the
version of the kernel module (and that the module has been reloaded if
there have been any upgrades - `dmesg` or `kern.log` are good places to
check that).
Cheers
