FS1> FreeSWITCH Version 1.4.15~64bit ( 64bit) FS2> FreeSWITCH Version 1.4.5~64bit ( 64bit) I would say that these are not "absolutely" identical. As the FreeSWITCH development team never sleeps it is likely that there are differences in the code that you now see. The first thing is to bring both machines up to the same release before comparing behaviors. Another suggestion is to confirm your G.729 license and configuration, if you are decoding that codec. Perhaps one machine has the necessary file(s) in the correct locations and the other machine does not? Hope this helps.

Hello Everyone! I have two installations of FS with absolutely identical configurations. Both has SIP profiles with proxy-media enabled. But on freeswitch@internal> version FreeSWITCH Version 1.4.15~64bit ( 64bit) I have values in read_codec/write_codec variables at CDRs: "read_codec":"PROXY","write_codec":"PROXY" but on another one freeswitch@internal> version FreeSWITCH Version 1.4.5~64bit ( 64bit) I have: "read_codec":"G729","write_codec":"G729", "read_codec":"PCMA","write_codec":"PCMA", etc... So Why? -- Yours sincerely, Vladimir Getmanshchuk
