I know this has been suggested in the past (last year), but I'd like to see G.722 looked at again as a codec for use in the Obi family of products.
The old saw has always been that a standard telephone will never make use of the extended range of frequencies, but there is an entire world of broadcast telephone hybrid equipment that will plug into an RJ-11 just as easy as a Trimline phone can.
Comrex (with their STAC/VIP) system has seen fit to adopt G722 into their broadcast hybrids. Perhaps Obi can be the lower cost alternative.
While we're at it, why not SILK and/or OPUS?

G.722 higher audio bandwidth codec sounds like fun to experiment with, particularly OBi to OBi. It is license free, or at least patent free, according to http://en.wikipedia.org/wiki/G.722
