show final SIP INVITE before going out - sr-users

10 Apr 2024


      hi,
i have kamailio with TLS
i dont have homer and voipmonitor with TLS decryption doesnt work
how can i check final SIP INVITE (after all rewrites/modifications) 
before is send to the peer?
tried
onsend_route {
           if ($rm == "INVITE") {
                         xlog("L_INFO", "Final SIP Message before 
Sending: $mbu\n");
           }
}
but record-route/via are different than reality (checked with sngrep 
with TLS disabled)
kamailio log
  Record-Route: <sip:;r2=on;lr;ftag=b0d1d4ce-...
  Record-Route: <sip:10.10.10.10;r2=on;lr;ftag=b0d1d4..
  Via: SIP/2.0/UDP 30.30.30.30:5080;TH=div;rport;branch=z9hG4bK
sngrep
  Record-Route: <sip:9.9.9.9;r2=on;lr;ftag=246bdf1c...
  Record-Route: <sip:9.9.9.9;line=sr-Jf7BrWSBdWSzrD

10.10.10.10 - private kamailio ip (fictional)
30.30.30.30 - ip of  SIP PBX (caller)
9.9.9.9 - public kamailio ip
