Hello,<BR>
<BR>
I have done some more detailed testing today and am still seeing the problem. I am using Kamailio 3.1.3.<BR>
<BR>
I added the following to the beginning of my route{ } section:<BR>
<BR>
<BLOCKQUOTE>
if (nat_uac_test(flags))<BR>
xlog("NAT'd\n");<BR>
<BR>
</BLOCKQUOTE>
I then tested the following scenarios using X-Lite 4:
<UL>
<LI>Flags = 1, TCP: NAT detected, UDP: NAT not detected
<LI>Flags = 2, TCP: NAT detected, UDP: NAT not detected
<LI>Flags = 4, TCP: NAT detected, UDP: NAT not detected
<LI>Flags = 8, TCP: NAT not detected, UDP: NAT not detected
<LI>Flags = 16, TCP: NAT detected, UDP: NAT not detected
<LI>Flags = 32, TCP: NAT not detected, UDP: NAT not detected
</UL>
<BR>
The REGISTERs (for TCP and UDP) sent by X-Lite were (with domain and user name obscured here):<BR>

I tried 63 (all), 55 (all but SDP), and 19 (from the sample configuration file).<BR>
<BR>
I will try it again today.<BR>

i don't know which param you tried, but nat_uac_test("2") and
nat_uac_test("1") works for me.
