But ACK and BYE definitely are separate transactions. :-) You can refuse to believe me,
but it’s still true.

Hi again,
I found a solution based loadbalance approach but I'm not sure whether it might cause
an issue for other things. Because ACK and BYE are not in a different transaction, I put
this at route[RELAY] as following;
if (is_method("ACK")) {
$duri= $ruri;
t_relay();
exit;
}
My kamailio's aim is to dispatch calls to Asterisks that located in a farm and relay
calls come from Asterisk to Outside.
Is it fine?

Hi
You're definitely right, but they must be in the same Dialog, but my case it
doesn't recognize it as it is in any current dialog.

Subject: Re: [SR-Users] Transaction Matching Failed - ACK BYE
Hi,
End-to-end ACKs (to confirm 2xx reply to INVITE transaction) and BYEs
are all separate transactions in their own right; they share a common
dialog with the initial INVITE request, but not a transaction. Why do
you expect them to match a known transaction?

Hi All,
I'm trying to establish a topology with Kamailio which is located between Asterisk
and Outside.
My issue is "transaction matching failed" (t_check_trans failed). That means
Kamailio does not recognise ACK & BYE message to forwards. I had a check on email list
and google but found nothing.
I'm using it with record_route.
SIP signalling and part of kamailio.cfg is below. Is there any suggestion?
route[WITHINDLG] {
if (!has_totag()) return;
if (loose_route()) {
route(DLGURI);
if (is_method("BYE")) {
setflag(FLT_ACC); # do accounting ...
setflag(FLT_ACCFAILED); # ... even if the transaction fails
}
else if ( is_method("ACK") ) {
xlog("ack is came: $si:$sp\n");
route(NATMANAGE);
}
else if ( is_method("NOTIFY") ) {
record_route();
}
route(RELAY);
exit;
}
if (is_method("SUBSCRIBE") && uri == myself) {
route(PRESENCE);
exit;
}
if ( is_method("ACK") ) {
if ( t_check_trans() ) {
route(RELAY);
exit;
} else {
exit;
}
}
sl_send_reply("404","Not here");
exit;
}
route[NATMANAGE] {
#!ifdef WITH_NAT
if (is_request()) {
if(has_totag()) {
if(check_route_param("nat=yes")) {
setbflag(FLB_NATB);
}
}
}
route(RTPPROXY);
if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))
return;
if (is_request()) {
if (!has_totag()) {
if(t_is_branch_route()) {
add_rr_param(";nat=yes");
}
}
}
if (is_reply()) {
if(isbflagset(FLB_NATB)) {
if(is_first_hop())
set_contact_alias();
}
}
#!endif
return;
