First, do a 'show translation' in the asterisk console to confirm that asterisk is definitely not supporting the translation. If it doesn't support it, you'll see a '-' instead of a number in the column and row for ilbc. Debian's, and possibly other distributions binaries, seems to only support ilbc in passthrough mode because of 'non-free' issues with the codec. I assume there is a patent or something attached to it. I believe you can build your own Asterisk to get around the issue, and in fact I asked the same question a while back and I seem to remember (but I'm not sure) that someone pointed me to a pre-compiled version in someone else's Debian repository that included the ilbc transcoding stuff. hth James _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
