Re: [SR-Users] Path & Loose Route

Hello,

set debug=3 in kamailio.cfg and look at log messages in syslog.

If you find it too verbose, use dispatcher module and set debug level only for core and rr modules to 3.

Cheers, Daniel

Hi Daniel,

I've added some more logging and can see loose_route() is returning -1

• route calculation has been unsuccessful.

Is there a way of finding out why this is the case?

Kind regards, Luke

I added the below xlog lines into my script:

xlog("L_NOTICE", "Before loose_route: $si -> $ru - $du\n");
xlog("L_NOTICE", "Before record_route: $si -> $ru - $du\n");
xlog("L_NOTICE", "After both: $si -> $ru - $du\n");

Which generated the below output in syslog:

Seems that the destination URI is never set, the Route header is
below:

Route: <sip:201@10.10.2.5:5072
<http://sip:201@10.10.2.5:5072/>>;lr;received=sip:[PUBLIC_IP]:45126

The use_received modparam for path is also set to 1.

Any idea's/suggestions are greatly appreciated :)

Kind regards,
Luke

    Morning Gents,

    Firstly, thanks for taking the time to reply :)

    Kamailio is doing the NAT detection and simply acting as a
    passthrough to FreeSWITCH (which handles all SIP registrations
    etc).

    Will setup the log lines shortly and share the results.

    kamailio -V outputs;

        Hello,

        yes, loose_route() should be used there. Can you add a log
        message and print $ru and $du before and after
        loose_route() in config and then send the result to this
        mailing list?

        Btw, what version of Kamailio are you using?

        Cheers,
        Daniel

        Is it correct to use loose_route() along side the path
        module?

            Hi Daniel,

            Yep, I've got the below in my kamailio.cfg

            modparam("path", "use_received", 1)

            Kind regards,

                Hi all,

                Currently trying to use Kamailio as a
                passthrough to some FreeSWITCH boxes.

                When receiving an invite from FreeSWITCH which
                contains a Route header including received
                information, example below;

                Route: <sip:201@10.10.2.5:5072
                <http://sip:201@10.10.2.5:5072>>;lr;received=sip:[PUBLIC_IP]:45126

                When using loose_route() Kamailio still send the
                invite to the rfc1918 address instead of the
                received IP:PORT in the Route header.

                Am I misunderstanding how this should work?

                if you use path module, have you enabled the
                option to use the received parameter?

                Cheers,
                Daniel
