I’m not totally sure what you are trying to accomplish but proxy_media is completely unnecessary and undesired for what you are doing. It should ONLY be used in the case where you are trying to pass codecs we don’t know about at all. Take a look at the codec negotiation page on freeswitch.org/confluence <http://freeswitch.org/confluence> and I think you will find your answers. I don’t think you need a custom mod looking for events with what you have described so far.

In FS document of media proxy mode:
FreeSWITCH has no control or even understanding of other SDP parameters. Look like I have to find another way, like writing a custom module listening on specific event. Any suggest?
Thanks to all of you. rgds,

Hi @Michael, you were right, I'm intentionally using media_proxy for FS, since I want to reduce CPU usage on FS machine.
In this case, I just want to limit the codecs used for each endpoint, and codec negotiation will be handled by them.
e.g: caller use PCMA, PCMU, GSM by its own in INVITE, I want to limit the callee to only use PCMA,GSM.
Look like `absolute_codec_string` is not what I'm looking for right? Any way out?

using proxy_media is my best guess but can’t tell with this little info.

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.
