Do I set the dlg_manage() function in the correct part of kamailio.cfg ?? I set it before
sending Invite message to remote side.
Any help would be great :)

Hi Henning,
Thank you for your response. I have checked with debug mode, here is the result; It
can't find the dialog that is why it sends "404 Not Here" even though callid
is the same.
Dialog that is kept in DB:
dialog memory records
dialog:: hash=1056:7783
state:: 4
ref_count:: 2
timestart:: 1600091398
timeout:: 90338404

callee_cseq:: 0
callee_route_set:: <sip:remote_sipserver;lr>
Debug output for BYE message:
NOTICE: acc [acc.c:317]: acc_log_request(): ACC:
transaction answered:
timestamp=1600091398;method=BYE;from_tag=as7cf5b3da;to_tag=as00b3f8a9;call_id=18f82088676a5d7f7c94e4f96c34a41f@asterisk_ip;code=404;reason=Not

Bye request header:
BYE sip:90850532xyzt@kamailio_ip SIP/2.0
And this is how I used dlg_manage() in Kamailio cfg (In RELAY):
if (src_ip == x.x.x.x/26) {
if (is_method("INVITE|ACK")) {
setflag(FLT_DLGINFO);
dlg_manage();
$var(x) = $tU;
$var(y) = $(var(x){s.striptail,11});
$var(recieved)='';
sql_pvquery("cb", "select ipaddress from prefixes
where prefix = $var(y)", "$var(recieved)");
uac_replace_from("sip:$fU@$var(recieved)");
xlog("L_WARN","$var(recieved)\n");
remove_hf("Contact");
append_hf("Contact: <sip:$fU@$var(recieved)>\r\n",
"Call-ID");
$fs = "udp:" + $var(recieved) + ":5060";
}
}
if (!t_relay()) {
sl_reply_error();
}

Subject: RE: Kamailio does not forward BYE to Asterisk
Hello Egemen,
have you tried to debug it and find out why the BYE is not routed in this particular case
from Kamailio? You already mentioned the R-URI, what is in this particular BYE? Is
Kamailio listening on all VLAN IPs? Just to share some ideas.
About the performance question, I know of some installation that have about 5-10
interfaces on a box and did not heard of problems so far.
The main topic to consider here (iMHO) is that it gets a bit complicated to handle many
different interfaces in one kamailio, so for that reasons it might be a good idea to split
it to different VMs or instances.
Cheers,
Henning

Subject: [SR-Users] Kamailio does not forward BYE to Asterisk
Hi all,
I have an infrastructure with Kamailio (reg), Asterisks farm, and Kamailio (4.3) proxy
which dispatches calls.
Trunk-1 (Vlan_A)
Kam(reg) <> Asterisk Farm (5) <> Kam(proxy) <> Trunk-2
(Vlan_B)
Trunk-3 (Vlan_C)
For each trunk, I have to use the IP of the VLAN interface in "contact header".
That means when I need to send a call to Trunk-1 I have to set Vlan_A IP address on the
contact header. I have achieved that by rewriting Contact Header.
###
remove_hf("Contact:");
append_hf("Contact: <sip:$fU@$var(recieved)>\r\n", "Call-ID");
#by using db
###
But this causes a problem, Kamailio does not forward the BYE message that comes from
Trunk-X to Asterisk (In before, the BYE message had Asterisk IP in R-URI). However, when I
use topoh module it forward properly for one trunk. But I can not set multiple mask IP in
topoh module.
I'm using the dialog module and I thought it can handle all requests in one dialog to
forward to the correct asterisk but it did not.
Is there any suggestion for this case?
And also how many sub-interfaces can Kamailio handle for a good performance? Or do you
suggest multiple Kamailio instances instead of multiple sub-interfaces on one server?
