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

Regarding the mediaproxy-ng documentation
special features can't be
invoked without usage of 'ng' protocol provided by rptmediaproxy-ng.
Unfortunately there is no info about rtpproxy-ng module itself. Haven't
found it at Sipwise GitHub site.
You can get it either as a patch file here:
https://github.com/sipwise/kamailio/blob/master/debian/patches/sipwise/rtpr…
Or by checking out the branch rfuchs/rtpproxy-ng in the regular Kamailio
repository.
cheers
