How to free DSP resources on CME for hardware conference?

I'm having trouble freeing DSP resources for hardware conference option.

The platform is UC520, CME4.2 with 12.4(11)XW7 IOS.

It has following built-in interfaces: 4FXO, 4FXS, 1MoH

It also has a PRI wic.

I'm using just the 2 FXO channels and 12 chanels on PRI card.

In this case 24 channels are used on DSPs (the sys. has 2 DSPs=32ch,

12 used for ISDN, 2 for MoH, 4 for FXS and 4 for FXO),

and I need one hole DSP for hardware conference.

I can shut down the unused FXO and FXS interfaces, but I got the

information that shutting them down won't free channels reserved for them,

due to hardware allocation of DSP channels for built-in cards.

Is it possible to free DSP channels allocated by built-in FXO and FXS ports?

No, it is not possible.
