Unless you want to spend loads of money on prototyping an VoIP IC that does 48KHz, then be my guest and build one On Mon, Sep 26, 2011 at 9:32 AM, Steve Underwood <steveu@coppice.org> wrote:

Are there any hardware phones that support 48 Khz Celt and automated/mass deployment?
Craig. Most of the pure VoIP chipsets aren't capable of running at 48k samples/second, so off the shelf phone hardware platforms probably won't cut it. The phones with video capabilities might have 48k sample/second facilities. 2009/6/30 Jason White<jason@jasonjgw.net>:

Everyone has this need for lower bandwidth calls... I tend to march the other way. 48kHz baby! (btw you can do 48kHz in the same bandwidth as a single ulaw call) 48khz Celt (celt@48000 in your codec preferences) sounds wonderful with FreeSWITCH. To test, run two FreeSWITCH instances, both with mod_portaudio. This also works well in 48khz conferences.
I wouldn't use G.729 even if it weren't encumbered by patents - it's G.711, G.722, G.722.1 and (my current favourite) Celt all the way. Steve
