Working on a proof of concept with Kamailio 5.5.2 (Installed via
kamailio-5.5.2-0.el8.centos.x86_64 RPM from rpm.kamailio.org).
Also note that this is using the LUA interface
Running a simple SIPp scenario without registration. Routing is set with in Lua:
KSR.dbg("EP: ksr_route_relay Check for Base Route\n");
if KSR.is_INVITE() and KSR.siputils.has_totag() < 0 then
KSR.dbg("EP: ksr_route_relay Base Route\n");
--KSR.sl.send_reply("503", "OLGX Debug");
KSR.setdsturi("sip:192.168.1.14:5060");
--KSR.pv.sets("$du", "sip:192.168.1.12:5062");
end
The problem is that Kamailio is dropping the ACK to the 200 OK from the UAS. Wireshark
shows that the UAS is retransmitting the 200 OK and the ACK is not being forwarded from
the UAC to the UAS.
Within the Lua config script:
-- Handle requests within SIP dialogs
function ksr_route_withindlg()
if KSR.siputils.has_totag() < 0 then return 1; end
KSR.dbg("EP: ksr_route_withindlg has to-tag, it is within a dialog\n");
-- sequential request within a dialog should
-- take the path determined by record-routing
if KSR.rr.loose_route() > 0 then
ksr_route_dlguri();
if KSR.is_BYE() then
KSR.setflag(FLT_ACC); -- do accounting ...
KSR.setflag(FLT_ACCFAILED); -- ... even if the transaction fails
elseif KSR.is_ACK() then
-- ACK is forwarded statelessly
KSR.dbg("EP: ksr_route_withindlg Forwarding ACK\n");
ksr_route_natmanage();
elseif KSR.is_NOTIFY() then
-- Add Record-Route for in-dialog NOTIFY as per RFC 6665.
KSR.rr.record_route();
end
KSR.dbg("EP: ksr_route_withindlg loose route calling
ksr_route_relay\n");
ksr_route_relay();
KSR.dbg("EP: ksr_route_withindlg exit\n");
KSR.x.exit();
end
if KSR.is_ACK() then
if KSR.tm.t_check_trans() > 0 then
-- no loose-route, but stateful ACK;
-- must be an ACK after a 487
-- or e.g. 404 from upstream server
KSR.dbg("EP: ksr_route_withindlg is ACK calling
ksr_route_relay\n");
ksr_route_relay();
KSR.dbg("EP: ksr_route_withindlg exit\n");
KSR.x.exit();
else
-- ACK without matching transaction ... ignore and discard
KSR.dbg("EP: ksr_route_withindlg Unknown ACK exit\n");
KSR.x.exit();
end
end
KSR.sl.sl_send_reply(404, "Not here");
KSR.dbg("EP: ksr_route_withindlg exit after 404\n");
KSR.x.exit();
end
And logs for the ACK:

I’ve been trying to figure this out for days and don’t know what’s wrong here.

You’re right that SIPp is not adding record route.
I tried adding the ‘rrs’ flag as shown on the default scenarios but did not work.
Working SIPp scenarios would be appreciated.
Thanks

Seems you forgot to add record route to invite, as a result there is no Route header in
ACK, so loose route fails.
Additionally there is no contact alias, so routing via alias also fails.
Also it seems you are not creating SIP transactions and dialogs in script, you just
blindly receiving sip request from one end and throwing it out to the other end!
So only possible way to route ACK is to set destination URI, same way you do for INVITE.
You will have to do that for EVERY sip request, unless you make your script intelligent
enough to create and recognize sip transactions & dialogs properly.
Hope this helps.

Subject: [SR-Users] Kamailio dropping ACKs
Working on a proof of concept with Kamailio 5.5.2 (Installed via
kamailio-5.5.2-0.el8.centos.x86_64 RPM from rpm.kamailio.org
<http://rpm.kamailio.org/>).
Also note that this is using the LUA interface
Running a simple SIPp scenario without registration. Routing is set with in Lua:
KSR.dbg("EP: ksr_route_relay Check for Base Route\n");
if KSR.is_INVITE() and KSR.siputils.has_totag() < 0 then
KSR.dbg("EP: ksr_route_relay Base Route\n");
--KSR.sl.send_reply("503", "OLGX Debug");
KSR.setdsturi("sip:192.168.1.14:5060");
--KSR.pv.sets("$du", "sip:192.168.1.12:5062");
end
The problem is that Kamailio is dropping the ACK to the 200 OK from the UAS. Wireshark
shows that the UAS is retransmitting the 200 OK and the ACK is not being forwarded from
the UAC to the UAS.
<PastedGraphic-2.png>
Within the Lua config script:
-- Handle requests within SIP dialogs
function ksr_route_withindlg()
if KSR.siputils.has_totag() < 0 then return 1; end
KSR.dbg("EP: ksr_route_withindlg has to-tag, it is within a dialog\n");
-- sequential request within a dialog should
-- take the path determined by record-routing
if KSR.rr.loose_route() > 0 then
ksr_route_dlguri();
if KSR.is_BYE() then
KSR.setflag(FLT_ACC); -- do accounting ...
KSR.setflag(FLT_ACCFAILED); -- ... even if the transaction fails
elseif KSR.is_ACK() then
-- ACK is forwarded statelessly
KSR.dbg("EP: ksr_route_withindlg Forwarding ACK\n");
ksr_route_natmanage();
elseif KSR.is_NOTIFY() then
-- Add Record-Route for in-dialog NOTIFY as per RFC 6665.
KSR.rr.record_route();
end
KSR.dbg("EP: ksr_route_withindlg loose route calling
ksr_route_relay\n");
ksr_route_relay();
KSR.dbg("EP: ksr_route_withindlg exit\n");
KSR.x.exit();
end
if KSR.is_ACK() then
if KSR.tm.t_check_trans() > 0 then
-- no loose-route, but stateful ACK;
-- must be an ACK after a 487
-- or e.g. 404 from upstream server
KSR.dbg("EP: ksr_route_withindlg is ACK calling
ksr_route_relay\n");
ksr_route_relay();
KSR.dbg("EP: ksr_route_withindlg exit\n");
KSR.x.exit();
else
-- ACK without matching transaction ... ignore and discard
KSR.dbg("EP: ksr_route_withindlg Unknown ACK exit\n");
KSR.x.exit();
end
end
KSR.sl.sl_send_reply(404, "Not here");
KSR.dbg("EP: ksr_route_withindlg exit after 404\n");
KSR.x.exit();
end
And logs for the ACK:

In my opinion, the carrier that you send a call, send ACK to RURI different
than Contact header value in your "200 OK".

No, i didn't mean to add RR to SIPp, which is an
endpoint. The problem is
with your kamailio, which is a sip proxy here. Just look at default
kamailio.cfg file that is shipped with RPM package. You will get the idea.
It has lots of comments which explains most of the stuff in there.
As for SIPp, the default call scenario is fine. However, you may want to
add RTP stuff there for proper call setup (i.e. with audio).

You’re right that SIPp is not adding record route.
I tried adding the ‘rrs’ flag as shown on the default scenarios but did
not work.
Working SIPp scenarios would be appreciated.
Thanks

Seems you forgot to add record route to invite, as a result there is no
Route header in ACK, so loose route fails.
Additionally there is no contact alias, so routing via alias also fails.
Also it seems you are not creating SIP transactions and dialogs in script,
you just blindly receiving sip request from one end and throwing it out to
the other end!
So only possible way to route ACK is to set destination URI, same way you
do for INVITE. You will have to do that for EVERY sip request, unless you
make your script intelligent enough to create and recognize sip
transactions & dialogs properly.
Hope this helps.

Subject: [SR-Users] Kamailio dropping ACKs
Working on a proof of concept with Kamailio 5.5.2 (Installed
via kamailio-5.5.2-0.el8.centos.x86_64 RPM from rpm.kamailio.org).
Also note that this is using the LUA interface
Running a simple SIPp scenario without registration. Routing is set with
in Lua:
KSR.dbg("EP: ksr_route_relay Check for Base Route\n");
if KSR.is_INVITE() and KSR.siputils.has_totag() < 0 then
KSR.dbg("EP: ksr_route_relay Base Route\n");
--KSR.sl.send_reply("503", "OLGX Debug");
KSR.setdsturi("sip:192.168.1.14:5060");
--KSR.pv.sets("$du", "sip:192.168.1.12:5062");
end
The problem is that Kamailio is dropping the ACK to the 200 OK from the
UAS. Wireshark shows that the UAS is retransmitting the 200 OK and the ACK
is not being forwarded from the UAC to the UAS.
<PastedGraphic-2.png>
Within the Lua config script:
-- Handle requests within SIP dialogs
function ksr_route_withindlg()
if KSR.siputils.has_totag() < 0 then return 1; end
KSR.dbg("EP: ksr_route_withindlg has to-tag, it is within a dialog\n");
-- sequential request within a dialog should
-- take the path determined by record-routing
if KSR.rr.loose_route() > 0 then
ksr_route_dlguri();
if KSR.is_BYE() then
KSR.setflag(FLT_ACC); -- do accounting ...
KSR.setflag(FLT_ACCFAILED); -- ... even if the transaction
fails
elseif KSR.is_ACK() then
-- ACK is forwarded statelessly
KSR.dbg("EP: ksr_route_withindlg Forwarding ACK\n");
ksr_route_natmanage();
elseif KSR.is_NOTIFY() then
-- Add Record-Route for in-dialog NOTIFY as per RFC 6665.
KSR.rr.record_route();
end
KSR.dbg("EP: ksr_route_withindlg loose route calling
ksr_route_relay\n");
ksr_route_relay();
KSR.dbg("EP: ksr_route_withindlg exit\n");
KSR.x.exit();
end
if KSR.is_ACK() then
if KSR.tm.t_check_trans() > 0 then
-- no loose-route, but stateful ACK;
-- must be an ACK after a 487
-- or e.g. 404 from upstream server
KSR.dbg("EP: ksr_route_withindlg is ACK calling
ksr_route_relay\n");
ksr_route_relay();
KSR.dbg("EP: ksr_route_withindlg exit\n");
KSR.x.exit();
else
-- ACK without matching transaction ... ignore and discard
KSR.dbg("EP: ksr_route_withindlg Unknown ACK exit\n");
KSR.x.exit();
end
end
KSR.sl.sl_send_reply(404, "Not here");
KSR.dbg("EP: ksr_route_withindlg exit after 404\n");
KSR.x.exit();
end
And logs for the ACK:
