Negative, that is the purpose of the dspfarm command. the dspfarm
command enables dsp sharing across the chassis.

The dsp services dspfarm command enables DSP farming for use as
ccm-registered conferece/transcode resources.

The answe to the specific query is that No, you may _not_ use both
PVDM AND PVDMII at the same time to provide DSPFarm resources to
callmanager from within one IOS Router.

The old DSPs use the old skinny stack (No dsp farm profiles) the New
ones use the New stack, with the DSP Farm profile configs. you may
_not_ use them both at the same time, that is not supported.

you CAN use BOTH types of PVDM Modules at the same time for the
purposes of TDM Voice termination. You may only use ONE at a time for
purposes of registering to callmanager.
