Set debug=4 and watch the logfile while receiving the ACK. If you do not
see any log messages then the ACK is not received by Kamailio (maybe
some local iptables/connection tracker problem)

We are troubleshooting this issue almost for 2 days and we did not find
the solution yet. The thing is, that it does not enter even the config
file (we have some debug messages at the start, that do not show).
Otherwise we do not have any problem with ACK, but only this particular
ACK is not forwarded... Was there some bug related to parsing in 3.1.0
which would not print any error to syslog?

Seems like a loose routing issue. Are you loose routing in your
config file?

You can use something like wireshark on Kamailio server to see
if ACK packets go in right direction.
I had problem with ACK and BYE, and I saw that in some cases ACK
and BYE packets looped back in kamailio.
May be I used wrong client.

Hi folks,
I have a strange problem when Kamailio ignores ACKs in a
specific
scenario. The call flow is as follows:
A -> INVITE -> kamailio -> INVITE -> B
[omitting 100 and 180]
A <- 200 OK <- kamailio <- 200 OK <- B
A -> ACK -> kamailio
There are INVITE Xlogs, Reply ROUTE xlogs and media-proxy
logs in the
syslog. However there is no information about these ACKs. No
XLOGs are
printed even if there is one on the top of the main route.
"tcpdump -A -s0 -i any -n port 5060" receives this message
correctly:

My Kamailio version is kamailio 3.1.0 (i386/linux) 1e204f.
Does anybody knows where can be a problem?
How can I check whether Kamailio receives something?
