SPA525G - G722 Codec Negotiation

We are attempting to update phones for using the G722 codec.  However, when calls are placed with the "Use remote pref" set to yes, the remote caller will go up to HD whereas the callee stays at g711u.  The server is set for g711u, g729a, g722 for preferences ( so that all outbound calls are at a native g711u format ).

canreinvite is set to nonat for all extensions.  I suspect that the remote end is seeing that the callee end is set to g722, g711u, g729a and using their preferrred which is g722, however, the callee does not switch over to use this as well.

Not sure if this is a problem with the phone negotiation or the server?

Ideally, we would have all outbound calls not show up as HD on the phone and all internal calls show up with HD.  Just want to ensure that users are recieving the experience the phone is reporting.

Any suggestions?
