If you have a H323 GW and only require G729 to be used e.g pign across a WAN do you really need any of the following?
voice class codec 2
codec preference 1 g729r8
codec preference 2 g729br8
codec preference 3 g711ulaw
Since the default per dial-peer is G729
If your scenarios work with G729r8 then you do not need to use a voice class codec on your dial-peers. VOIP dial-peers default to using G729r8 and it sounds like in your scenario that is fine.
