Hello All! After finishing with RTPproxy protocol support, I'm working on a RTPproxy-ng protocol support in Wireshark. I've just submitted an initial version with a very basic functionality:
https://code.wireshark.org/review/#/c/268/
So far there is no support for RTP/RTCP dissection based on a RTPproxy-ng replies, no transaction matching, no expert functionality, and the rest of functionality already existed in the RTPproxy dissector is also missing, but I plan to add it back shortly.
I'm on a very early stage with RTPproxy-ng protocol support so I can't really advise anyone to try it so just fyi.
Sorry for the crossposting.
