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

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