IMHO it's a bit of a marketing gimmick at this stage. I played with it some months ago with Snom equipment and it sounds great when it's supported end-to-end, but most of the rest of the world can only support 8KHz 8-bit PCM at best.

The question is: does the N900 support the AMR-WB codec?
IIRC it came with gstreamer plugins for it, but wasn't advertising the codec in SIP SDPs. No idea what it does for cellular calls.
