[SR-Users] Kamailio 5.4.4 and Siptrace

[Daniel-Constantin Mierla]

Hello,

logs indicate that the siptrace is engaged when the reply is sent out:

May 03 15:40:30  kamailio[6259]:  5(6267) DEBUG: siptrace
[siptrace_hep.c:496]: pipport2su(): the port string is 5060
May 03 15:40:30  kamailio[6259]:  5(6267) DEBUG: siptrace
[siptrace_hep.c:496]: pipport2su(): the port string is 58530
May 03 15:40:30  kamailio[6259]:  5(6267) DEBUG: <core>
[core/proxy.c:264]: mk_proxy(): doing DNS lookup...
May 03 15:40:30  kamailio[6259]:  5(6267) DEBUG: siptrace
[siptrace_hep.c:184]: trace_send_hep3_duplicate(): setting up the
socket_info

Can you watch the network traffic with ngrep/wireshark and check if the
reply is actually sent over?

Cheers,
Daniel
