Conference Bridge no Voice

Trying to Create a HW conference bridge with 4 sessions and up to 32 particapents per conference. Call Manager version 7.1.2

Created a hardware conference bridge on Cisco 2811.    

The problem is, that when I add this DSP farm to the media resource group, all looks good. I see the resources being used when initiating a conference but there is no voice.

Here are the PVDM's installed on the router.

NAME: "PVDMII DSP SIMM with three DSPs on Slot 0 SubSlot 4", DESCR: "PVDMII DSP SIMM with three DSPs"
PID: PVDM2-48          , VID: NA  , SN: FOC09411T4N

NAME: "PVDMII DSP SIMM with one DSP on Slot 0 SubSlot 5", DESCR: "PVDMII DSP SIMM with one DSP"
PID: PVDM2-16          , VID: NA  , SN: FOC093626P7

          

Configuration for the DSP farm on the router

Hi Alex,

The IP address for 0/0.16 is on our voice subnet. The conference bridge is registered with the CM.
