Hey all, Any way to log destination IP and proto of SIP responses? I'd tried to use majority of the pseudovars, but they all just return <null>.

$sel(via[2].host) should give the 'destination' of the reply, provided that the original request wasn't from behind NAT and one single proxy in between UAs. Don't take my answer for granted, as I don't think it's complete and/or accurate. On Wed, Jan 2, 2019 at 5:11 PM Andrew Chen <achen(a)fuze.com> wrote:

My bad, thought you wanted the source IP... So to get it right, you want to know to which IP belonging to Kamailio a response came in? On Wed, Jan 2, 2019 at 18:11 Joel Serrano <joel(a)textplus.com> wrote:

Hello, you can use accounting module to log them.You can append new variables, modparam("acc", "log_extra", "src_user=$fU;src_domain=$fd;src_ip=$si;" "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd") in addition, there is a onsend_route to help what you need. https://www.kamailio.org/wiki/cookbooks/5.2.x/core#onsend_route cookbooks:5.2.x:core [Kamailio SIP Server Wiki]<https://www.kamailio.org/wiki/cookbooks/5.2.x/core#onsend_route> This is the second section of the configuration file, containing the directives to load modules and set their parameters.

Hello, like Joel said, in reply_rpute or onreply_route use $si and $pr to get the source ip and protocol of the reply. If you need it in failure_route, then use $T_rpl($si) and $T_rpl($pr), from the TMX module like was suggested by another response. If none of these is what you want, then explain where you needed to see what is possible. Cheers, Daniel On Thu, Jan 3, 2019 at 7:06 AM YAS0 CANER <caner_yaso(a)hotmail.com> wrote:

First, thanks guys for all the responses. These are great suggestions. So my Kamailio needs to forward SIP responses back to ether client or server side, depending on where the initial SIP method originated from. Client side generally is behind NAT. When forwarding the response, I want to log the destination IP to I'm forwarding it to and which protocol it is using by using some sort of pseudovariable. The reason I want to do this is for troubleshooting purposes to show that Kamailio is sending it where it suppose to send it. After trying different options, I actually ended up using the Via header to log where the responses are sending it back to: $sel(via[2].host) - destination host $sel(via[2].transport - protocol to use Note that I'm not sure if this is the best and accurate option for what I'm doing, but I'm using this assuming the fact that my next hop is in via[2].

Like I said, via[2] will not be accurate if the original request came from behind NAT, as VIA[2] in most cases will be a private IP (provided UAC didn't perform any far-end NAT-traversal tricks). The final destination of a reply will be decided upon performing routing on the reply message, taking into account *rport *and *received* values in the VIA headers. That being said, I don't know the true answer, but very interested to find out as well. On Thu, Jan 3, 2019 at 9:34 AM Andrew Chen <achen(a)fuze.com> wrote:
