Hi all. I'm having problems with an indialog ACK request which is not being
routed correctly.
I call loose_route and print:
$du=sip:MYIP:2443;transport=ws;r2=on;lr=on;did=1d1.7702;nat=ws
$route_uri=sip:MYIP;r2=on;lr=on;did=1d1.7702;nat=ws
But when I call
check_route_param("nat=ws") I get false result.
version: kamailio 5.1.4
any hints?
cheers,
Jon

Hi!
What is your original packet, before calling loose_route?

Hello,
I see MYIP in R-URI and then just MY in the Route headers. Are they
different or the same value? If the same value, is the sip server
address? if yes, then R-URI is matching local address (myself) and that
means it is a strict routing and the R-URI is the route processed at
that step. Likely the contact address from 200ok gets replaced with
server address somewhere in the path of signaling.
Cheers,
Daniel

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"))

Even with client on the same host as the server, the port should be
different. R-URI of ACK has port 5060, like on of the Route headers, so
I assume only kamailio is using that port.
R-URI for ACK has to be the contact URI from 200ok and if it is kamailio
ip:port, then that is what loose_route() is considering to be the Route
hop based on strict routing rules. The R-URI must be different than
kamailio ip:port (and transport) to actually consume from Route headers
via loose processing.
Try to figure out why ACK has the address of Kamailio in R-URI and not
the address of the callee.

understood. Thank you. I will check another capture tomorrow in the lab server.
