Hi, I have two clients using different codecs. Client A: PCMA, H264 Client B: G729, H264 Agent: PCMA,G729,H264 FS:PCMA,G729,H264 Now agent could only accept calls of client A but not from client B. When I change the codec order of FS to G729,PCMA,H264, then agent could accept client B but not from client A. I have tried these settings below and all in vain. 1) add <action application="set" data="inherit_codec=true"/> in diaplan (inbound-late-negotiation is true) 2) add <action application="export" data="nolocal:absolute_codec_string=G729,H264"/> in diaplan B. 3) add {absolute_codec_string='G729,H264'} in callcenter application, syntax error Here is the diaplan. <extension name="Test Call Center"> <condition field="destination_number" expression="^555$"> <action application="sleep" data="1000"/> <action application="callcenter" data="555@default"/> </condition> </extension> How can I configure to accept both clients? Any advice would be appreciated. Jimmy --- 由於 avast! 防毒軟體已開啟防護，所以此封電子郵件將不受病毒及惡意軟體的侵害。 http://www.avast.com
