One data point. Our ACDs for our international calling card type traffic increased by ~15% when we dropped G.729 and went to G.711. Whilst G.729 on its own is fine, a typical call path would be cell->us->cell, so there'd be at least three separate encodings and decodings. Call quality under these circumstances isn't great, and taking out one set of compression help noticeably.
