I am running FreeSWITCH Version 1.0.3 on a centos 5.2 x64 server and ekiga 3.2.0 on a client computer. I am able to register the ekiga client with the freeswitch server but when I dial an extension to join a conference I get the following error message: [ERR] switch_core_io.c:327 switch_core_session_read_frame() Codec RAW Signed Linear (16 bit) decoder error! I have the celt codec loaded on both the server and the client computer. This is the full output when dialing an extension: 2009-04-12 12:56:34 [INFO] mod_dialplan_xml.c:233 dialplan_hunt() Processing joseph schmidbauer->4800 in context default 2009-04-12 12:56:34 [INFO] mod_sofia.c:1301 sofia_receive_message() Asked to send early media by sofia/internal/joe@192.168.1.125 2009-04-12 12:56:34 [INFO] mod_sofia.c:1342 sofia_receive_message() Ring SDP: v=0 o=FreeSWITCH 1239529036 1239529037 IN IP4 192.168.1.125 s=FreeSWITCH c=IN IP4 192.168.1.125 t=0 0 m=audio 26358 RTP/AVP 116 101 a=rtpmap:116 CELT/48000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off - - - - a=ptime:10 a=sendrecv 2009-04-12 12:56:34 [NOTICE] mod_sofia.c:1345 sofia_receive_message() Pre-Answer sofia/internal/joe@192.168.1.125! 2009-04-12 12:56:34 [NOTICE] mod_conference.c:1934 conference_loop_output() Channel [sofia/internal/joe@192.168.1.125] has been answered warning: decode error [ERR] switch_core_io.c:327 switch_core_session_read_frame() Codec RAW Signed Linear (16 bit) decoder error!

I've tried using the svn version of freeswitch (as of yesterday) and i got the exact same error. Any input would be appreciated. Thanks!
