I found this message concerning VAD and was wondering whether VAD has been
ported to fixed-point in the latest version?

Here's a quick summary:
In narrowband, the encoder and decoder are all ported to fixed-point for
CBR between 4 kbps and 18.2 kbps. Only the 2 kbps (vocoder) and 24.6
kbps modes still have a few floats left. Most of wideband is also
ported, but there are some float operations left. The packet loss
concealment is also done, but not the VAD/VBR. The jitter buffer isn't
converted, but there's not many float ops there in the first place. The
preprocessor and echo cancellor aren't converted and there's lots of
float stuff there.
