thank you for saying which package had the dll.
I was able to find it, and make a mirror here of the dll file required
I was then able to add it to mplayer project, by adding this to ~/.mplayer/codecs.conf:
info "verint g729"
format 0xA104 ;untested
guid 0xe1d97f0c, 0x47d0, 0x416b, 0x97, 0xc6, 0xcd, 0xf5, 0xdc, 0x30, 0xd6, 0xf4
mplayer can play your sample .wav file. but i only tested this on windows.
it might work in linux for you to convert your files with 32bit mplayer compiled with dmo/dshow win32 codec support. assuming you follow those steps (download dll file to a location mplayer looks for codecs (usually /usr/local/lib/codecs) and add that info to codecs.conf).
simply mplayer -ao pcm g729stereo.wav
let me know if it works for you, this is an alternative until ffmpeg gets support for it.
