Full-band audio is in the proposed requirements
http://tools.ietf.org/html/draft-valin-codec-requirements-02#page-11
Voice quality should be (near) transparent towards the high end of the  
specified bitrates.

What you can't get is the immunity to network jitter that streaming  
brings. Voice calls are real-time and therefore use a much smaller  
buffer.
