Voice Troubles (3825 and NM-2CE1T1-PRI)

Hi and thanks in advance for any assistance rendered.
I've got a 3825 running 12.4(9T) with advanced IP services and security.
Modules/vwics installed are:
1 x NM-2CE1T1-PRI (controller T1 1/0 and 1/1)
1 x 2 port FXS vwic (voice-port 0/1/0 and 0/1/1)
1 x 4 port FastEthernet Switch vwic (fastethernet 0/0/0 - 0/0/3)
1 x 1 port Fiber based FastEthernet interface (fastethernet 2/0)
The router also has one PVDM2 (not sure of the particular size) occupying 1 of the 4 available PVDM slots.
After working on this all week, I haven't gotten far by hopefully have learned a lot.
After setting my ISDN Switch type, framing, and line coding on the T1 controller (controller t1 1/0), I set a pri-group using all 24 channels (1-24).
At that point (from past experience) I expect to be able to go to config mode for voice-port 1/0:23 and do a "no shut". Well this doesn't work and the voice-port doesn't show up after configuring the pri-group.
Voice-port 0/1/0 and 0/1/1 work just fine.
Questions:
1. Do the FXS ports use the PVDM2 that is installed or do they support themselves?
2. Is the reason that the voice-ports ( for the T1) don't show up, because I don't have enough (or large enough) PVDM2s installed?, or does the NM-2CE1T1-PRI just not support voice?
3. Or am I just doing something wrong or forgetting to do something?
This is connecting to a Redcom IGX set as switchtype DMS100.
If I install an HD type T1 Module with the PVDMs self-contained ( on the module, not using the router PVDMs) the configuration works fine.
I know of several others with the same setup that are encountering the same problem and they're not getting anywhere either. So it's not just me
.
Thanks,
George

While not familiar with the NM-2CE1T1-PRI, I know that with VWIC-xMFTs the IOS will tell you that you don’t have enough DSP resources and will create the PRI group accordingly.
Try this for the NM-2CE1T1-PRI stup:
