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:

And this is how I used dlg_manage() in Kamailio cfg (In RELAY):

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?
