Hello Daniel,
This is correct, we can get the forwarding message with $snd(buf) on the
onsend_route. But unfortunately, there have no any sip_trace version to do
log with a given message as method argument.
Actually right now, we using trace_mode=1 setup. But we need to do log only
for Kamailio to UAC side, not to do log for both side.
Thanks,
Salah
