Except no handsets yet support CELT, so you'll have to transcode locally to a mainstream codec such as G711 (uLaw/aLaw),until handsets support this. Sadly, unless some of the larger proprietary PBX offerings provide this codec, it's unlikely to happen anytime soon. Handset manufactures are only just starting to tweak towards Asterisk settings, let alone publicly 'support' it.
