Hello Everyone,
Looks to be related to the team interface after all, which is strange.
Have confirmed that after getting rid of the LACP/Team interface, media is flowing as expected after kernelization.
I simply:
Restarted for good measure, and made some test calls. All worked perfectly with media traversing the public and carrier interfaces as expected.
rtpengine -v1
> Version: git-HEAD-5bf2c50a
> CentOS Stream release 8
> Linux 4.18.0-373.el8.x86_64
Is it worth opening an issue in the rtpengine repo?
Cheers,
Tim

Appreciate the help Richard!
Media is traversing the team0 link <> one of the two carrier vlan’s as per:
team0: connected to Team connection 1
"team0"
team, 50:9A:4C:XX:XX:XX, sw, mtu 1500
ip4 default
inet4 203.x.x.x/27
route4 203.x.x.x/27 metric 350
route4 default via 203.x.x.x metric 350
carrierX180: connected to carrierX180
"carrierX180"
vlan, 50:9A:4C:XX:XX:XX, sw, mtu 1500
inet4 10.x.x.x/28
route4 10.x.x.x/28 metric 401
route4 202.x.x.x/27 via 10.x.x.x metric 401
route4 10.x.x.x/30 via 10.x.x.x metric 401
inet6 fe80::xxx/64
route6 fe80::/64 metric 1024
carrierY178: connected to carrierY178
"carrierY178"
vlan, 50:9A:4C:XX:XX:XX, sw, mtu 1500
inet4 10.x.x.x/28
route4 10.x.x.x/28 metric 400
//CUT//
inet6 fe80::xxx/64
route6 fe80::/64 metric 1024
Cheers,

Evening!
I ditched firewalld and swapped to configuring iptables manually…
I’ve also made some basic calls with media going in/out of the same interface and I’m still seeing the audio stop completely or become one-way once kernelized.
On the two different interfaces, I get no-way audio once kernelized. Weird!
Could this be related to the kernel module being unsigned (running CentOS 8 Stream)?
kernel: xt_RTPENGINE: loading out-of-tree module taints kernel.
kernel: xt_RTPENGINE: module verification failed: signature and/or required key missing - tainting kernel
kernel: Registering xt_RTPENGINE module - version git-HEAD-5bf2c50a
systemd-modules-load[781]: Inserted module 'xt_RTPENGINE'
No, that is expected and perfectly fine.
Have been pulling my hair out!
[root@blahblah zgadmin]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
rtpengine udp -- anywhere anywhere
ACCEPT all -- anywhere anywhere ctstate RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
//cut//
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain rtpengine (1 references)
target prot opt source destination
RTPENGINE udp -- anywhere anywhere RTPENGINE id:0
That looks fine. How about the actual network setup? Any network namespaces, policy routing, or other unusual setup in place?
Cheers
