Hi!

I'm trying to get Kamailio working as a traffic capture on a same machine with other PBX software installed.

Actually, traffic is mirrored with

iptables -A PREROUTING -t mangle -i eth0 -p udp --dport 5060 -j TEE --gateway 127.0.0.2
iptables -t nat -A PREROUTING -d 127.0.0.2 -p udp --dport 5060 -j DNAT --to 127.0.0.1:5062

Kamailio request route is super simple

request_route {

    xlog("L_ALERT", "[SIP-PACKET] Got packet [F=$fu R=$ru D=$du M=$rm IP=($si:$sp $Ri:$Rp) ID=$ci]\n");

    drop;

}

I was trying to get Kamailio just listen on interface 127.0.0.1:5062, but no luck

listen=udp:127.0.0.1:5062

Next was to use sipcapture module with following parameters

loadmodule "sipcapture.so"

modparam("sipcapture", "db_url", "text:///tmp/")

modparam("sipcapture", "raw_socket_listen", "127.0.0.1:5060-5062")

modparam("sipcapture", "raw_interface", "lo")

modparam("sipcapture", "promiscious_on", 1)

Also no luck. Means Kamailio can't see packets, but I see em with wireshark on lo interface.

What is best way to get it working? Or I'm missing something?

Thanks!
