I have mod_opus loaded. Trying to find the documentation as to what the name of the CODEC is for including it in codec preferences. I tried OPUS, but that doesn't seem to work. <X-PRE-PROCESS cmd="set" data="global_codec_prefs=OPUS,speex@16000h@20i,speex@8000h@20i,G7221@32000h, G7221@16000h,G722,PCMU,PCMA,GSM" /> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=speex@16000h@20i,PCMU,PCMA,GSM" /> Trying to get Jitsi to negotiate 2012-11-10 12:54:22.039330 [DEBUG] sofia.c:5475 Remote SDP: v=0 o=1000 0 0 IN IP4 192.168.99.198 s=- c=IN IP4 192.168.99.198 t=0 0 m=audio 5020 RTP/AVP 96 a=rtpmap:96 opus/48000 a=extmap:1 urn:ietf:params:rtp-hdrext:csrc-audio-level a=zrtp-hash:1.10 29740c437bd6d867c08a8854b65368c5052c70ec0b463a06f748062657529239 thanks in advance, I googled the list, and docs don't seem to find the answer.
