Comments:	By: pj (pj) 2007-11-30 10:47:11.000-0600 maybe this issue, should be better categorized as chan_sip/codecshandling By: Olle Johansson (oej) 2007-12-04 09:11:28.000-0600 Please try again with latest trunk. I fixed this in rev 89698, hopefully. http://svn.digium.com/view/asterisk?view=rev&revision=89698 By: pj (pj) 2007-12-04 10:05:27.000-0600 iLBC is now correctly removed from combined codecs list, but why is g722 as 'unknown', even if g722 is shown in core show translation and is enabled in peer config?  Codec Order  : (g729:20,gsm:20,ilbc:30,g722:20) [Dec  4 16:58:35] Found RTP audio format 111 [Dec  4 16:58:35] Found RTP audio format 112 [Dec  4 16:58:35] Found RTP audio format 8 [Dec  4 16:58:35] Found RTP audio format 0 [Dec  4 16:58:35] Found RTP audio format 97 [Dec  4 16:58:35] Found RTP audio format 101 [Dec  4 16:58:35] Peer audio RTP is at port 192.168.164.154:10270 [Dec  4 16:58:35] Found unknown media description format SIREN for ID 111 [Dec  4 16:58:35] Found unknown media description format G7221 for ID 112 [Dec  4 16:58:35] Found audio description format PCMA for ID 8 [Dec  4 16:58:35] Found audio description format PCMU for ID 0 [Dec  4 16:58:35] Found unknown media description format RED for ID 97 [Dec  4 16:58:35] Found audio description format telephone-event for ID 101 [Dec  4 16:58:35] Capabilities: us - 0x1502 (gsm|g729|ilbc|g722), peer - audio=0xc (ulaw|alaw)/video=0x0 (nothing)/text=0x0 (nothing), combined - 0x0 (nothing) By: Olle Johansson (oej) 2007-12-04 10:21:46.000-0600 G7221/16000 is unsupported by asterisk, so it's unknown.
