Sorry, it's the same value.

The subscriber is in the same IP as the proxy. It's a lab version of a webrtc
client. client using port 42088, nginx using port 3002 and kamailio using port
5060 internally


asterisk (OUT) --> 5060 kamailio nginx 2443 --> ua 42088



Anyway, after loose route I don't know why nat=ws isn't detected. $route_uri
printed in xlogs shows this:

 $route_uri=sip:MYIP;r2=on;lr=on;did=1d1.7702;nat=ws

According to the doc:

"The function checks if the URI parameters of the local Route header
(corresponding to the local server) matches the given regular expression. It
must be call after loose_route()"

 Example 1.15. check_route_param usage
if (check_route_param("nat=yes"))
