Hello,
Yes, second option.
Here is the diff between current module and the original one:

Hello,
did you update to latest version in the branch or you applied the patches?
If first option, then give me the output of 'kamailio -v'.
If second, can you send the patch that resulted for you, because there were two commits?
Cheers,
Daniel

Hello Daniel,
Thank you for the patch.
I tried it (change received_test() by received_via_test()), but the result is the same.
The INVITE was the same than the one already sent.
Regards,
Igor.

Hello,
didn't get the time to look at the INVITE trace before, checked it now and indeed, there was an issue revealed by the extension of received_test() function to check the presence of rport parameter. The issue was there with the presence of received parameter in Via, but that was not common and thus this testing function was ok for most of the case.
I just pushed patches to fix it in master, 4.2 and 4.1 branches. Let me know if works as expected now.
Cheers,

Hello Daniel,
Here is the SIP message:
[…]
I can confirm that the issue is present with 4.2.1 too.
No problem with 4.1.4.
The SIP message and the configuration are the same in both cases.
Thank you.

Hello,
the commits you refer to were not related to nat_uac_test() function.
Can you send the sip message for which you used the test and is different than in the old versions?
Cheers,

Hello,
I reviewed the changelogs.
I can see the following updates that could change the previous behaviour:
commit 42897d422b60edeac393201326a3e71318445e62
Author: Daniel-Constantin Mierla <miconda@gmail.com>
Date: Mon Sep 22 22:04:39 2014 +0200
core: add received parameter to via if rport parameter is present
- required by RFC3581, section 4.
(cherry picked from commit a1e96cbd5a3b43598c59cb50693e6b739801b804)
commit a52c0024723a59d90c3c3966d5deadaf8b0d4440
Author: Daniel-Constantin Mierla <miconda@gmail.com>
Date: Sun Sep 28 12:48:53 2014 +0200
core: helper functions to get addr and port to be used in signaling from socket info
(cherry picked from commit c725f1dec14863e069bfd1e5c26857a1005528d5)
But I can't explain why the same nat_uac_test doesn't behaves the same between the two versions.
Regards,
Igor.

Hi Amit,
The config is the same between the two version. Even this line.

Hi
You should compare this line in your configuration file.
if (nat_uac_test("18")) {
It may be using different parameters.Regards,

Hello,
I can reproduce the issue on a pre-production system.
So, I downgraded to 4.1.5.
Here is the difference:
The INVITE comes into NATDETECT:
route[NATDETECT] {
xlog("ENTERING NATDETECT routes\n");
#!ifdef WITH_NAT
force_rport();
if (nat_uac_test("18")) {
if (is_method("REGISTER")) {
fix_nated_register();
} else {
add_contact_alias();
}
setflag(FLT_NATS);
xlog("NAT_UAC_TEST OK\n");
}
#!endif
return;
}
With Kamailio 4.2.0, the NAT_UAC_TEST returns true whereas with 4.1.5 returns false.
I also look at the “force_rport”. I’m not sure if it’s related, but with 4.2.0, the Via looks like:
Via: SIP/2.0/UDP PST_GW:5060;received=PST_GW;rport=5060;branch=z9hG4bK-34d5-1416308856-4847-441\r\n
In 4.1.5:
Via: SIP/2.0/UDP PST_GW:5060;rport=5060;branch=z9hG4bK-2e3d-1416311184-4886-146\r\n
The received parameters is not added. Note that PSTN_GW refers to a public IP address (out of RFC1918 and Carrier Grade NAT).
Regards,
Igor.

Hello,
Since I done the upgrade of Kamailio into 4.2.0, there are, at least, one new case where the RTPProxy is launched.
When I got an INVITE from my PSTN Gateway, for unknown reason (and not for all calls), Record-Route is append with nat=yes. I looked into an old trace and this behaviour didn’t exist.
What could have changed that can explain this?
Regards,
Igor.
