I'm still working my way through this new feature.  I've got a TAC case 
open (Polycom's are still only making 128K calls, and often no video), 
but still no "cook book" explanation for how this is supposed to work, 
or if it even makes sense.

With a Polycom HDX 4002 at a site and a Codian 3241 PRI gateway, I can 
use the built-in GK in the Codian, and register prefixes "1" and "011". 
  The endpoints register to the Codian and can dial "normally" (no user 
training required).

Even if I get this feature to work on the 2851, it seems like I'm still 
stuck because 12.4(20)T doesn't have a built-in GK featureset option, so 
the endpoints can't register to the 2851; I would need the IP address of 
the 2851 in the dial field on the Polycom, and the actual phone number 
that I want to dial in the "extension" field, which is awkward.

Latest IOS that seems to have the GK functionality is 12.4(2)T, and that 
one wouldn't have the channel bonding feature...

Thoughts?
