Hello, Just to let you know that I tried also with 4.2.1 and the issue is the same.

I can see the following updates that could change the previous behaviour: commit 42897d422b60edeac393201326a3e71318445e62 Author: Daniel-Constantin Mierla &lt;miconda(a)gmail.com <mailto: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.

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).

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?
