Hi!
Just suggest someone already tried mediaproxy-ng with conversion RTP/SRTP. Few examples of options' usage would be very appreciated! May authors bring them into the tutorial?
E.g. caller invokes RTP/SAVPF profile (SIP over WS), but calle supports RTP/AVP only. During the simple tests I've put rtpproxy_offer("spFRWOCII1-") into the INVITE route. However it doesn't work as was expected: mediaproxy offers the same SDP for callee. SIP 488 (Not Acceptable) as a result for caller.
