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.

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
