Hi Gabriel,

The problem I see is that g729 is protected by very expensive patents.

If FreeSWITCH were to encode their sound files in g729, they would
have to pay a base fee of at least 10 or 15 thousand dollars (that's last time i
checked, and i don't recall if this is a yearly payment or not), plus a smaller fee
for each file they encoded, and would likely have to pay an additional fee each
time the files were downloaded.

You may have to do the encoding yourself on this one...

Once they are encoded, the plan sounds feasible.. I don't know the status on
g729 in FreeSWITCH though.

I've pretty much standardized on using g729 as the codec of choice for
the users connecting to my FS installation, primarily due to the users I
have that are on very slow connections and all of my carriers support
g729, so no need to transcode.

The sounds files that comes with FS are raw PCM files. Since FS is
unable to currently transcode to/from g729, is there any way to use
sounds files that are in the g729 format, such that it is technically
still "pass-through" on the FS side and no transcoding is required?

Ideally, I'm looking to install pre-coded g729 files for voicemail and
have FS playback those files when someone logs into voicemail. I haven't
tried simply replacing the files in the sounds directory, what I would
prefer is to have a separate directory structure with g729 sound files
and have FS detect the codec in use and automatically playback the files
for the appropriate codec?

Thanks Much...
