[SR-Users] kamailio & vmware

[Jean Cérien]

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 !
