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.

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].

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

Oh my bad, I got now.
on reply route , you can get some variables. Have you tried "TMX module
Pseudo-Variables"

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.

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. It contains the
directives loadmodule and modparam.In the default configuration file starts
with the line setting the path to modules (the assignment to mpath core
parameter.. Example of content:

onsend_route
onsend_route {
if(to_ip==1.2.3.4 && !isflagset(12)){
log <http://www.opengroup.org/onlinepubs/009695399/functions/log.html>(1,

$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.

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>.
Thanks.
