Hi there, i had installed on all my servers the codec_g729b which is the old voiceage, so a month ago i updated the codec to codec_g729a. After that i started to get this message on my asterisk console: Dec 16 09:19:26 NOTICE[1288699200]: rtp.c:293 process_rfc3389: Don't know how to handle RFC3389 for receive codec 256 Dec 16 09:19:26 NOTICE[1288699200]: rtp.c:264 process_rfc3389: RFC3389 support incomplete. Turn off on client if possible Im only using g729 on all my servers, i have some IAX conections with only g729 too. I think its a negotiation problem but with the old version i didnt have this error. If anyone knows how to fix this would be very helpful. Thanks for your help Carlos Andres Medina --------------------------------- Do you Yahoo!? Send holiday email and support a worthy cause.
