Hi List, I got some trouble with using `absolute_codec_string` param. My call scenario is pretty simple: caller <--> FS <--> callee. My caller compose `m=audio 7078 RTP/AVP 8 0 101` in its INVITE, and I'm doing `<action application="bridge" data="{absolute_codec_string=PCMU,GSM}sofia/gateway/callee/$1"/>` in the dialplan. But FS still use `m=audio 22952 RTP/AVP 8 0 101` in the INVITE to the callee. not sure what I'm missing, helps would be appreciated. Note that when I'm using `originate` application in fs_cli, things are good. `originate {absolute_codec_string=PCMU}sofia/gateway/caller/100 &bridge({absolute_codec_string=PCMA}sofia/gateway/callee/100`. I have FS with proper behavior in transcoding, caller has `m=audio 31184 RTP/AVP 0 101` received, and callee has `m=audio 21922 RTP/AVP 8 101` received. rgds, Loi Dang Thanh Phone : 84.1224.735.448 Email : loi.dangthanh@gmail.com
