Hello All, I'm getting the below error while only in pass-through mode (proxy_media=true) but it's fine when the disable-transcoding is set on the sofia profile. [WARNING] switch_core_codec.c:703 Codec G723 Exists but not at the desired implementation. 8000hz 20ms [ERR] switch_core_media.c:2285 Can't load codec? This error does not occur in case of another pass-through codec(G729) Here are my settings when in proxy media mode: Sofia Profile: inbound-late-negotiation = true inbound-codec-negotiation = greedy (tried scrooge) I also tried rtp-autofix-timing=true (no luck) DialPlan: proxy_media=true bridge FS version tried: 1.5.13b & 1.2 FS Logs: with proxy-media (failed) http://pastebin.freeswitch.org/23205 with disable-transcoding is set (success) http://pastebin.freeswitch.org/23206 A pcap file can be supplied off the list.
