  Throughout most of this thread I've been using G.729 and G.729a
interchangeably.  That's sloppy on my part.  Most of the time I meant
G.729a because that is what most people (everyone?) uses.

  I was under the impression the quality difference wasn't that
significant.  I can't say if I've ever knowingly used "true" G.729.
It certainly doesn't help that G.729a is allegedly completely
compatible with G.729, to the point where I don't think it's even
valid to use "G.729a" or annexa in an SDP...
