Hi,
Do you need further
information? Actually, I am not sure if the process is
normal, there‘s no problem with the call at least.
Could it be caused any problem
if all clients do fix_nated_register?
Best Regards,
Rex

Hi Alex,
Thanks for your reply.
ICE/STUN haven’t been activated
by our clients. All transmission traffic pass through a
proxy server. Below is the screenshot of a normal call
process.
Best Regards,
Rex

It's a tell-tale sign of an
end-to-end ACK from the caller not being forwarded
properly to the callee. The server should not be
forwarding such an ACK "to itself"; this suggests that
its Request
URI may be improperly constructed (it should be
equivalent to the remote Contact URI of the callee in
the 200 OK message), or that its Route headers are
somehow incorrect (they should mirror the Record-Route
set in the 200 OK).

weird that the calls always drop after 32s while the
callee is using public ip. Also, Server forwards ACK to
itself with UDP, instead of forwarding to callee
with TLS.
