As far as common VoIP codecs and endpoints that people use today, not really, no. ;)

Most people's sound cards are limited to 48kHz operation, also.  Really, it's that going the extra mile there wasn't terribly difficult, and we're interested to see if anyone makes a practical use of it; maybe not now, but perhaps in the future.

CELT is the only general-use audio codec we're aware of that can operate at 96kHz.  We wanted to make sure we covered for that, and for one step beyond.
