G.729E
Greetings list,
Does anyone have any information (providers' support) about G.729E?
Voip-info.org came up empty, the implementers guide from the ITU wants
my credit card and the rest of the pages I found simply made a few
comparisons between it and iLBC.
>From what I understand, the codec is supposed to play nicely on lower
power hardware but I can't find much more info t...

Signaling tones in Speex
Hi all,
Has anyone tried conveying signaling tones (DTMF) through speex? If so, can
i get an idea of the lowest bit-rate at which I can do so with 'tolerable
distortion'. G.728 does so and G.729E (11.8 Kbps mode) is 'claimed' to do so
but even if true, G.729 (rather G.729I - 11.8/8/6.4 kbps) does not allow me
to go below 6.4 kbps if needed. Basically I am looking for a single codec
which would allow me to play with multiple (low) bit-rates within voice and
switch to a higher bit-rat...
