Hi Rupa, Thanks for your feedback. I am currently running proxy mode, but whenever I try to force G.729 on in-bound and out-bound calls, I get an error in my logs to the effect the G.729 is only a pass-through codec. Both originator and reciepient have G.729 codecs. Have you seen this before ? Regards, Ahmed. 2009/12/23 Rupa Schomaker <rupa@rupa.com>

Hello people,
Can someone please clear the following ambiguities with codecs:
Are we definitively able to run pass-through codecs (e.g. G.729) in Proxy Media mode, or does FS need to be running in bypass-media ? the Wiki is not clear in this regard
Yes, you can use proxy media, bypass media, or even regular mode if you don't transcode (special for g729). Proxy media is really a special hack that should only be used for T38 passthrough. If you are using it for other purposes, think about it some more....
When an A-leg has negotiated a pass-through media codec, can the B-leg be transcoded into a non-pass-through codec, and vice-versa ? think A-leg incoming with a G.729 codec, and target for B-leg needs to be setup with a GSM-codec, say
That would require transcoding - which can't be done if the codec is pass-through.
Where in the developer's set of documentation are codecs discussed ? I would like to start porting some code of mine for G.729a/b/ab form a ti DSP platform to FS. FS lacking full G.729 support is proving quite a hindrance, and there is no clear direction from the dev community as to when the same will be available. Incidentally, any news on this effort ? where are we with code, and what's an ETA for a Beta ?
I'd say look at the broadvoice or other simple self-contained codecs are done. Currently the only supported g729 solution is to use a digium board with mod_dahdi_codec.
I don't have any info on a software based g729 solution.
On the same lines as (3) above, there is a codec dev template in the source tree. Again, where can I find documentation relating to this ? the template has hardly any docs at all.
Best regards and warm wishes for a Merry Christmas and a great New Year to one and all.
Ahmed.
