it would really help me to be able to use completely stateless

<p>Hello,</p>
<p>you have to keep in mind that Kamailio is a SIP packet
router, not a telephony engine. If 180 and 200 replies are
part of a call is not something that Kamailio recognize at its
core. Its main goal is to route out as fast as possible what
is received, by executing the configuration file script. Now,
a matter of your configuration file, processing of some SIP
messages can take longer than processing other. And the
processing is done in parallel, a matter of children parameter
(and tcp_children, sctp_children).<br>
</p>
<p>With that in mind, a way to try to cope better with the issue
you face is to set route_locks_size parameter, see:</p>

<p>Probably is what you look for.</p>
<p>But if you want more tight constraints, like when receiving a
180 after a 200ok and not route it out, you have to make the
logic in configuration file by combining modules such as
dialog or htable (as already suggested).</p>

worried about this scenario, because it's a symptom of
what may happen in other cases. For instance, I've
seen that this operator usually sends re-invites
immediate after sending ACK. This may create race
conditions like 3.1.5 of RFC5407<br>

I'd understand that one happens because of packet
loss, as it's in UDP's nature, but in this case it
would be artificially created by Kamailio. if there
was no problem at network level (packet loss, packets
following different path on the network and arriving
out of order), why Kamailio creates it? <br>
<br>
I'd expect that the shared memory is used precisely
for this. If an instance of kamailio receives a 200
OK, it could check on the shm and say "hey, another
instance is processing a 180 for this call. Let's wait
for it to finish" (*). I know there could still be a
problem, the instance processing the 180 undergoes a
context switch just after it receives the message, but
before writing to shm, but it would greatly reduce the
chance.<o:p></o:p></p>

our applications we use a SIP stack that always sends
messages to the application in the same order it
receives them, even though is multi-threaded and
messages from the network are received by different
threads. So, they really syncronize between them. Why
Kamailio instances don't?<br>
<br>
I am evaluating kamailio to use it as a dispatcher to
balance load against our several Application Servers,
to present to the operator just a couple of entrance
points to our platform (they don't want to establish
connections to each one of our servers). This operator
is very difficult to deal with. I am sure they will
complain something like "why are you sending messages
out of order? Fix that". The operator will be able to
see traces and check that messages entered the
Kamailio nodes in order and left out of order. They
will not accept it.<br>
<br>
(*) Not really "wait", as it would introduce a delay
in processing all messages. it should be like putting
it on a queue, continue processing other messages, and
go back to the queue later.<br>

<b>Subject:</b> [SR-Users] Kamailio propagates 180
and 200 OK OUT OF ORDER<o:p></o:p></p>

<p style="margin-left:70.8pt">Good day,<o:p></o:p></p>
<p style="margin-left:70.8pt">I am testing the
dispatcher module, using Kamailio as stateless
proxy. I have a pool of UAC (scripts in SIPP) and a
pool of UAS (also scripts in SIPP) for the
destinations. Kamailio version is
kamailio-5.3.3-4.1.x86_64.<o:p></o:p></p>
<p style="margin-left:70.8pt">Problem I have is, if
UAS responds 180 and 200 OK to Invite immediately,
sometimes they are propagated out of order. 200 OK
before 180, like this :<o:p></o:p></p>
<p

src="cid:part12.E6CB27B5.B0770C6E@gmail.com"
class="" width="597" height="209" border="0"><o:p></o:p></p>
<p style="margin-left:70.8pt">UAS is
172.30.4.195:5061. UAC is 172.30.4.195:5080.
Kamailio is 192.168.253.4:5070<o:p></o:p></p>
<p style="margin-left:70.8pt">Difference between 180
and 200 is just about 50 microseconds. <o:p></o:p></p>
<p style="margin-left:70.8pt">My guess is that both
messages are received by different instances of
Kamailio, and then because of context switches, even
though the 180 is received before, that process ends
after the processing of 200. However, I had the idea
that in order to avoid these problems the kamailio
processes synchronized with each other using a
shared memory. I tried using stateful proxy and I
obtained the same result.<o:p></o:p></p>
<p style="margin-left:70.8pt">By the way, anyone has
any idea about how Kamailio's share memory is
implemented? It clearly does not use the typical
system calls shmget(), shmat(), because they are not
shown by ipcs command.<o:p></o:p></p>
<p style="margin-left:70.8pt">Before posting here I
googled, but I couldn't find anything related to
this. I can't believe I am the only one who ever had
this problem, so I guess I am doing something
wrong...<o:p></o:p></p>
<p style="margin-left:70.8pt">Please, any help. I'm
really stuck on this.<o:p></o:p></p>
<p style="margin-left:70.8pt">Thanks.<o:p></o:p></p>
