Hello Andreas, Yes, that's what I had thought, but
I am actually seeing it using two different UDP ports towards Freeswitch (send=40036 and recv=40042) and two more ports towards SIP Client (send=40038, and recv=40040). I am wondering if there is any setting (or flag at compilation time) that will make it symmetric. This rtpengine is daemon only, (not using kernel module).
