In the case of conferencing, it will require the use of the entire DSP. On a PVDM2-16 there is only one DSP. Without a PVDM2-32 or large, you won't be able to configure both transcoding and conferencing. This explains the maximum sessions problem.
In this case if the call is coming into the conference bridge as G.729 I believe you're right that it will need to be transcoded in order to join the G.711 conference. I would have to lab this up to be sure. You could try configuringing your ephones with 'codec g729r8' and trying the conference with the WAN phone to see if this makes a difference. I'm not positive if the conferencing session on CME has to be 100% converted go G.711 or not.
The short answer is that you don't.... That isn't entirely true while at
