Hello,
If I understand correctly your email, you want the IP/Host of the
destination of the outgoing INVITE that is leaving a Kamailio box?
First of all, how are you forwarding the request? Are you using dispatcher
module?
Here are a couple of options:
1-
https://www.kamailio.org/wiki/cookbooks/5.3.x/pseudovariables#du_-_destinat…
(although
this depends on your config, it might not be set)
2- https://www.kamailio.org/wiki/cookbooks/5.3.x/core#onsend_route +
https://www.kamailio.org/wiki/cookbooks/5.3.x/pseudovariables#sndto_name
If you can describe a little more how you are doing things we might be able
to give you more information.
Joel.

Hi all,
I’m a newbie for Kamailio and working on a feature needs end-users’
destination IP in the first transferred/forwarded invite message.
Basically, our system/call flow is like:
ClientA -> Kamailio1 -> Kamailio2 -> ClientB
Invite from the clientA:
*tls:212.252.34.165:32980 <http://212.252.34.165:32980>*
*tls:172.21.193.100:5061 <http://172.21.193.100:5061>*
*INVITE sip:905364167881@testsip.tvoip.turkcell.com.tr:443

<sip%3A905364167881(a)testsip.tvoip.turkcell.com.tr>*
*CSeq: 20 INVITE*
*…*
Needed Ip (Client B’s IP 10.252.180.51 for this case) is in the INVITE row
of the forwarded message.
Invite to the Kamailio2 :
*udp:172.21.193.100:5060 <http://172.21.193.100:5060>*
*udp:172.21.193.98:5060 <http://172.21.193.98:5060>*
*INVITE sip:905364167881@**10.252.180.51**:36945;transport=tls SIP/2.0*
*Record-Route:

*CSeq: 21 INVITE*
*…*
When the first invite message receives, the dialog variables or sel(msg…)
parsed values belong to this first received message, as far as I understand
during the tests. However I need the forwarded invite message’s variables.
Even after t_relay in RELAY route, it looks the message I have is the first
one. So, I cannot reach this later IP in the forwarded invite message. As
far as I understand, bear with me here please, this IP manipulation
executes in t_relay function and in the C side of Kamailio. So, I cannot
find a way to do that in the our native scripts.
Is there any way to get it without diving C code’s abyss? Do you have any
idea about it? I would appreciate it, if I can get any help or any clue.
Thanks for all...
