    Do any of the cisco ip phone or any ip based phones support the 'cd quality audio' or 128k AAC-LD or
    is the 64k G.711 the best?

    if the phone is running sccp it supports 256 kbps voice. I believe it
    is a proprietary compression algorithm. As far as I know it only works
    when the phone is homed to Callmanager. the region the phone is using
    must use the "wideband" codec.
