Recently we update kamailio fromversion 4.1.1 to 5.2. In this new version we have facing following issue.

We tried to catch this message using t_on_reply and on_sl_reply but no luck. Actually we need to forward those message to another server using sip_trace. If using trace_mode=1 then all message forwarded perfectly. But I need to set correlation_id with sip_trace method. So we need to catch that message and tag the correlation_id with that. Could anyone please help me on this? Is there anything I missing or any way to fix this?

Thanks in advance,

Salah
