Many thanks for the help, I think I am getting closer, and obviously ;-) the issue is not caused by Kamailio !
under some load (still to confirm); when asterisk receives the relayed invite from K, it generates the reply message (100 trying) but this message does not reach the network, ie, I see the message in asterisk debug log, but not in the sngrep/pcap traces Again, thanks for the help !
