Move conference bridge from software to hardware

I am needing to move our conference bridge to being handled by a router instead of by cucm software. I have a 2811 with 2 pvdm2 in with a total of 80 dsp between them.  1-16 and 1-64.  Can anyone point me in the right direction to find exact step by step instructions for configuring them in the router and also how to configure call manager 9 to work with this and use the hardware instead of software?

ok so here is a link that covers the configuration on the router:

This is an older document so the CUCM part is really old.  In CUCM you will need to add it as an Enhanced Conference Bridge.   What you define as the register name will be what you will define in CUCM.

Here is another example of configuring the enhanced bridge with an udated version of CUCM.

Once you are done, make sure you put the hardware conf bridge in your media resource group.

One more note. We are just doing G711.  No other codecs. But could have up to 75 participants in one conference call.

ok you are not going to get 75 participants on a call with this conference bridge..

This doc shows you the limitations on how many users on a conference:
