Hi,
I am using openSER as a proxy for a simple SIP call (UAC <--> openSER <-->
UAS). openSER receives ACK from callee but doesn't send it to caller.
It seems openSER can not find a matching transaction, so it ignore and discard the
message.
if ( is_method("ACK") )
{
if ( t_check_trans() )
{
t_relay();
exit;
}
else
{
# ACK without matching transaction ... ignore and discard.\n");
exit;
}
Here is the message header:
Internet Protocol, Src: 10.0.0.174 (10.0.0.174), Dst: 10.0.0.160 (10.0.0.160)

Am I missing anything?

Hello,
seems are you doing record_route()/loose_route() processing, right? You
need to change the scenario of the sipp to handle the Record-Route
headers. The ACK should arrive to kamailio with a Route header.
Cheers,
Daniel
