_______________________________________________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:
INVITE sip:905364167881@testsip.tvoip.turkcell.com.tr:443 SIP/2.0
Via: SIP/2.0/TLS 100.64.13.139:56993;branch=z9hG4bK.GoiTxA4Ee;rport
From: <sip:905368601286@testsip.tvoip.turkcell.com.tr>;tag=WbINy0ypx
To: sip:905364167881@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 :
INVITE sip:905364167881@10.252.180.51:36945;transport=tls SIP/2.0
Record-Route: <sip:gearbox11.turkcell.tgc:5060;r2=on;lr;did=7f5.f572;nat=yes>
Record-Route: <sip:testsip05.tvoip.turkcell.com.tr:443;transport=tls;r2=on;lr;did=7f5.f572;nat=yes>
Via: SIP/2.0/UDP gearbox11.turkcell.tgc:5060;branch=z9hG4bK67ad.4e8e863f2475ab8d3053af0593548557.1;i=f
Via: SIP/2.0/TLS 100.64.13.139:56993;received=212.252.34.165;branch=z9hG4bK.1SYkXD1Me;rport=32980
From: <sip:905368601286@testsip.tvoip.turkcell.com.tr>;tag=WbINy0ypx
To: sip:905364167881@testsip.tvoip.turkcell.com.tr
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...
