Ok, that was probably too unclear. That's true, Klaus, rtpproxy works just fine with SRTP as it is just the RTP payload which gets protected and thus is shuffeled back and forwards without any changes hence no problems so far. The integration is about bridging between two clients when the proxy runs at the border of a network, say an internal UA talking RTP to the proxy, which itself talks SRTP to the other endpoint on the outside. This would probably require a change to the nathelper module as well, as it must be signalled to the rtpproxy when to actually process (protect/unprotect) the packets and what to do for which side.
