I have been looking into the freeswitch core and so far it has been a good journey. I am exploring the possibilities of integrating part of the media side of freeswitch with Intel's DPDK to process media frames at line rate bypassing the Linux kernel. In any case, Before I delve into the media related codes, I would like if someone could elaborate end explain the below three flags: (used (set/test) heavily in sofia and other places): CF_PROXY_MODE CF_PROXY_MEDIA CC_PROXY_MEDIA Best Regards, Dave
