[Freeswitch-users] Proxy Media and Codec Prefer

Dear All, I'm not sure it's bug or not ? I try to test codec negotate. with 3 FS box FS1 send PCMA to FS2 and FS2 send G729 to FS3 FS1 -----> [PCMU] ----> FS2 ------> [G729] -------> FS3 (10.20.2.49) My dialplan <action application="bridge" data="{absolute_codec_string='G729'}sofia/internal/2222@10.20.2.49:5080"/> It's work fine When i try <action application="set" data="proxy_media=true"/> <action application="bridge" data="{absolute_codec_string='G729'}sofia/internal/2222@10.20.2.49:5080"/> Call fail. because FS2 ignore absolute_codec_string='G729' and send only PCMU (I think by pass from FS1) It's bug or not ?
