[Freeswitch-users] sofia.c:5172 Codec Error! v=0

How do I identify the source of this error and fix it? 2011-03-09 16:02:42.845215 [ERR] sofia.c:5172 Codec Error! v=0 o=MxSIP 0 28211 IN IP4 x.x.x.x s=SIP Call c=IN IP4 x.x.x.x t=0 0 m=audio 5238 RTP/AVP 0 18 101 a=rtpmap:0 PCMU/8000 a=rtpmap:18 G729/8000 a=fmtp:18 annexb=no a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 I'm actually surprised that I'm even seeing this with proxy_media=true enabled. The codec list is correct and what are supported by both endpoints. <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G729,PCMU,PCMA"/> Thanks, Max
