[SR-Users] mediaproxy-ng documentation available

[Alexey Rybalko]

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.

Log events:

*[kamailio]*
...
 ERROR: rtpproxy-ng [rtpproxy.c:1229]: unknown option `s'
...
 ERROR: rtpproxy-ng [rtpproxy.c:1318]: proxy replied with error: Unknown
call-id
