[SR-Users] Problems migrating from rtpproxy/rtoproxy.so to rtpproxy-ng/rtpengine

Hi all, I'm currently running a pilot with kamailio 4.1.3 stable, and I would like to test WebRTC Capabilities. Websockets Support is runnig OK, and now I'm trying to deal with calls between WebTRC and legacy softphones. I have installed rtpengine (as it a replacement for old mediaproxy-ng), and it is running: rtpengine --table=0 --ip=192.168.0.197 --listen-udp=127.0.0.1:12222 As a first step, I'm trying to migrate the standard NAT handling configuration to the new module. (...) #loadmodule "rtpproxy.so" loadmodule "rtpproxy-ng.so" (...) #modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7624") modparam("rtpproxy-ng", "rtpproxy_sock", "udp:127.0.0.1:12222") NAT hanling is not working, and I catched this message from /var/log/syslog May 28 18:55:35 kamailio rtpengine[2474]: Failed to properly parse UDP command line '4547_3 d7:command4:pinge' from 127.0.0.1:60874, using fallback RE May 28 18:55:35 kamailio rtpengine[2474]: Failed to properly parse UDP command line '4545_4 d7:command4:pinge' from 127.0.0.1:57236, using fallback RE And from Kamailio's log: May 28 19:23:47 kamailio /usr/local/sbin/kamailio[4868]: ERROR: rtpproxy-ng [rtpproxy.c:1425]: rtpp_test(): proxy responded with invalid response May 28 19:23:47 kamailio /usr/local/sbin/kamailio[4869]: ERROR: rtpproxy-ng [rtpproxy.c:1425]: rtpp_test(): proxy responded with invalid response Is rtpproxy-ng module compatible with rtpengine? Best regards Luis.
